PVC Medical Compounds from Teknor Apex Now Span the Full Alternative-Plasticizer Range
Recognizing that interest in non-phthalate plasticizers is high among manufacturers of PVC medical devices, Teknor Apex Company has assembled a complete range of alternative plasticizers and incorporates them into compounds with equipment uncontaminated by previous processing of phthalates.
"Teknor Apex has redesigned its medical compound manufacturing facilities to ensure compliance with the stringent phthalate contamination specification of less than 1,000 parts per million now prevalent in most government and agency regulations," said Peter M. Galland, industry manager. "Our plants in the United States and Singapore are prepared to supply vinyl medical compounds spanning virtually the full range of plasticizer formulations, including phthalates and all important alternative types."
The table below briefly describes key alternative plasticizers. Galland noted that the Vinyl Division is well prepared to assist medical manufacturers in selecting the most appropriate plasticizer formulation for an application. Many of the plasticizers themselves are produced by the Chemicals Division of Teknor Apex.
Adipates Eg., DEHA (DOA).
Close to phthalates in cost.
More water extractable than DEHP.
Less compatible with PVC, increasing risk of exudation and resulting in surface tackiness.
Citrates Derived from citric acid.
More water extractable than DEHP.
Efficiency most closely resembles that of DEHP.
Dibenzoates Little used as PVC plasticizers thus far.
More water extractable than DEHP.
First introduced in Europe.
Viewed favorably on animal toxicity and solubility data.
DOTP Di-octyl terephthalate.
Classed as a non-phthalate.
Least costly alternative to DEHP.
Improved animal toxicity and less water solubility.
Metabolizes differently than DEHP.
In some uses, may exude, causing tackiness, unless properly formulated.
Trimellitates Eg., TOTM.
Most costly alternative in this list.
Less extractable in water than DEHP, other phthalates, citrates, adipates, and dibenzoates.
Could be more gel-prone.
Table 1: Alternatives to Phthalates Available in Medical-grade PVC Compounds
"Through no fault of the phthalate family of plasticizers for flexible PVC, market interest in replacing them is rapidly mounting in Europe and North America, particularly in the medical device sector," Galland said. "Although the U.S. Food and Drug Administration has continued to support the use of phthalates - including DEHP - in medical devices, mounting opposition from non-governmental organizations and now even the U.S. Environmental Protection Agency has device manufacturers scrambling for alternatives. And in Europe, an EU directive requires that devices plasticized with DEHP be identified as such starting in March 2010."
DEHP is still the most widely used, least costly plasticizer in medical-grade PVC.

Commencement of New PVB Resin Production Line in Europe
Kuraray Co., Ltd has executed production capacity expansion of PVB (poly vinyl butyral) resin (Brand Name; MOWITAL) by constructing one new line at its European subsidiary, Kuraray Europe GmbH ("KEG"). KEG has finished trial operation, and just started commercial production. The total annual capacity of PVB resin at KEG has been increased by this latest expansion to 39,000 tons.
PVB resin is made from PVA (polyvinyl alcohol) resin which was industrialized for the first time in the world in 1950. PVB resin is a raw material for the production of "PVB Film (Brand Name; TROSIFOL)" which is used as interlayer for architectural glazing and laminated safety glass for automotive, respectively. Furthermore, the demand of TROSIFOL as encapsulant of solar cell modules is increasing. Among other applications PVB resin is used as a binder in paint, printing ink, and ceramics.
The Kuraray Group will further enhance its vinyl acetate and Poval-related businesses on a global basis, while reinforcing the consistent production flow from PVA resin to PVB resin and film.
Kuraray was founded in 1926 for the purpose of commercializing synthetic rayon, which was cutting edge technology at the time. In 1950 during the post-World War II period, as Japan's first domestic producer of synthetic fiber based on original Japanese technologies, Kuraray became a world leader in the commercialization of PVA (poval) fiber under the KURALON brand, ushering in Japan's pioneering era in the chemical synthetic fiber industry.

BIOtech Products Gets Recognized for the Development of Biodegradant Polymer Additive
One of 10 products selected to receive the 2010 Environmental Stewardship Award from The Plastics Environmental Division of the Society of Plastics Engineers (SPE), is the path breaking new additive that turns polyvinyl chlorides into biodegradable polymers.
BIOtech Products, LLC is being recognized for the development of organometallic additives (BIOchem™) that make PVC and some other plastics biodegradable in biologically active landfills, while retaining or improving normal service life and processing of the plastic materials.
BIOflex, engineered using BIOchem™, has been the first truly environmentally friendly, biodegradable PVC, before which, PVC had been known to be immortal in the landfill & no degradation was found even after decades of landfill burial. BIOflex PVC is claimed to be landfill biodegradable under the conditions as simulated by ASTM D5526. Due to this breakthrough additive technology and also the huge market behind (PVC being one the main polymer used in the world), the BIOflex technology has been patented (filed in 2005 and granted in 2008). One of the current applications of such biodegradable PVC is outdoor PVC signage, made by Ultraflex Systems Inc. Environmental concern is influencing companies to take steps towards building a sustainable image, so it is not surprising to see leading companies like Disney requiring the use of BIOflex products in all their signs.

BIOflex PVC vinyl that has been in an accelerated landfill for 30 days
In order for any additive to work practically as a biodegradant on conventional non-biobased polymers (which are the bulk of all polymers consumed), the additive cannot allow degradation in the presence of oxygen and light because it would obviate the function of the conventional plastic product for any long term use. BIOchem™ works under anaerobic conditions by "micro-decomposition by micro-organisms" and not by "oxo-degradation or other similar process", thereby addressing the need to bring conventional thermoplastics into the realm of biodegradability with the caveat that the BIOchem™ containing product has to be disposed into controlled anaerobic landfill operations.
The additive works, although not completely understood, in part by inducing nano-hydrophilicity to a hydrophobic polymer thus providing a path for water so that anaerobic microbes can colonize the hydrocarbon given the controlled landfill conditions of darkness, no oxygen, anaerobic microbes, and high water content that stimulate the micro-organisms to secrete an enzyme that leads to chain scission, lowering molecular weight to the point of complete vulnerability to microorganisms. At this point the micro-organisms are able to metabolize the plastic further and produce valuable methane gas and soluble chloride fertilizer. The degradation is elemental and therefore the technology can also be viewed as sustainable.

Ampacet's High-Efficiency Antioxidant Masterbatch Allows Higher Recycled Content in Polyolefin Films
Ampacet has introduced a high-efficiency antioxidant masterbatch that protects reprocessed or recycled polyolefins from degradation during processing, allowing blown and cast film processors to use more recycled content without detrimental effects on aesthetic or physical properties. The new masterbatch is particularly beneficial in applications like clear packaging films, where cost-savings initiatives are driving use of more recycle, but gels are not tolerated. The masterbatch is also effective in repelletizing operations, where it adds value by restoring thermo-oxidative stability, enabling recycled resins to perform more like virgin resin.
Film processors want to improve the sustainability of their products by replacing virgin resin with reprocessed or recycled resin. Processors are also running their lines faster and at higher temperatures. This combination of severe processing conditions and materials that are more prone to degradation can result in crosslinking and gels. Ampacet's high-efficiency antioxidant masterbatch solves this problem by boosting the thermo-oxidative stability of recycled material. Because the antioxidant protects against degradation, gel-formation, and yellowing, processors can downgauge and/or use higher recycle content while maintaining film properties.
Ampacet's high-efficiency antioxidant masterbatch is cost-effective and typically can be used at low let-down ratios of 0.5 to1%. For example, "In blown film processing of a clarity application, 0.5% of the masterbatch reduced gels and allowed re-use of edge trim and scrap of up to 10% without any detrimental effects on physical or optical properties," reports Shawn Lucas, development manager at Ampacet. He adds, "In another case, adding 1% of the masterbatch during repelletizing allowed a cast film processor to increase the addition of repelletized material from less than 5% to greater than 15% in a critical application."
The masterbatch is approved for food-contact applications.
With 18 manufacturing sites located in 13 countries, Ampacet Corporation is a global masterbatch leader and offers the broadest range of custom color, special effect, black, white and specialty additive masterbatches for molding and a multitude of other processes and applications. Headquartered in Tarrytown, N.Y., Ampacet Corporation employs more than 1,500 people worldwide and operates technical and color development centers and manufacturing sites throughout the Americas, Asia and Europe.

Saluyot Joins Pineapple and Banana as Fiber Source
From delectable food to haute couture, saluyot, like pineapple and banana, can be a source of natural fiber for chic apparels. Researches have recognized the importance of banana leaf sheaths and pineapple leaves in producing cloth of exportable quality. Now comes saluyot stems.
The Philippine Textile Research Institute (PTRI) has developed new sets of earth-friendly yarns from polyester and stems of saluyot (Corchorus olitorius), being a rich source of natural fibers.
PTRI director, Dr. Carlos C. Tomboc, stressed the Institute's focus on studying non-traditional tropical fiber sources such as maguey (Agave cantala Roxb.), water hyacinth (Eichhornia crassipes), and saluyot in addition to abaca (Musa textiles Nee), anabo (Abroma augusta Linn), banana (Musa sapientum), kenaf (Hibiscus cannabinus L.), pineapple (Ananas comosus Linn.), and ramie (Boehmeria nivea L.) which PTRI has studied. The Institute is pushing for the use of fiber-rich plants in textile production to support the local industry in reducing its import of synthetic-based fibers from other countries.
PTRI's research trials show that saluyot stems when soaked in water for 21 to 24 days could yield at least 5% fibers. Spinning the treated fibers with polyester produced 80/20, 70/30 and 60/40 polyester/saluyot with yarn counts of 25-29Ne, which when woven, can produce fine, smooth, and blemish-free fabrics ideal for manufacturing garments.
Blends of saluyot and polyester fabrics can also be made into home textiles such as curtains/drapes, beddings, table runners and linens as well as raw material for nets, ropes, and other farm gears. In some countries, saluyot fabric is used as geotextile to prevent soil erosion and landslides.
PTRI continues its research trials in spinning saluyot fiber with cotton to increase the all-natural fiber component in producing saluyot fabric or burlap. According to PTRI researchers, other tests will also be performed to determine the ability of the fabric to resist deformation and the textile surface to resist wear by friction and other standard procedures to assure the product's quality.
The United Nations (UN) General Assembly declared as the International Year of Natural Fibres and has chosen saluyot as one of the 15 of the world's major natural fibers. PTRI is one with the UN recognizing saluyot fiber's potential in apparel, home, industrial, and geotextile applications.
About The Philippine Textile Research Institute
PTRI is the lead agency of the Department of Science and Technology in textile research and development. The Institute is dedicated to transfering technologies and rendering technical services, promoting the use of indigenous resources, and developing technical competence in textile production and quality assurance.

Angstron Patents New Class of Superior Nano Graphene Supercapacitor Electrode Materials
Nanotek Instruments, parent company of Angstron Materials Inc., has been issued U.S. Patent 7,623,340 for its development of a new high-performing class of meso-porous nanocomposites. The new nanocomposite provides a superior supercapacitor electrode material for uses that include hybrid electric vehicles (EVs), transportation and energy storage. The technology is based on the company's breakthrough discovery of nano graphene platelets (NGPs). Angstron, the world leader in production of NGPs, will make the nanocomposite material.
The NGP-based nanocomposite exhibits high levels of capacitance and electrical conductivity as well as demonstrating chemical stability and low mass density. Both NGPs and NGP-based nanocomposites can be mass produced cost-effectively when compared to carbon nano-tubes and fibers. Supercapacitors containing this advanced material offer the potential to supplement a battery used in an electric car to provide bursts of power needed for rapid acceleration. Until now, this critical requirement has been the largest technical hurdle to making battery-powered cars commercially viable.
In addition, supercapacitors must also be able to store sufficient energy to provide an acceptable driving range. The new NGP-based material makes it possible for a supercapacitor to meet weight and cost targets while combining adequate energy and power with a long cycle life. Angstron will provide the meso-porous NGP nanocomposites in two forms: NGPs coated with a thin layer of conducting polymer or surface functional groups and NGPs bonded by a conductive binder, coating, or matrix material such as a polymeric carbon. The platelets in these products are comprised of a sheet of graphite plane or multiple sheets of graphite plane with a thickness less than 10 nm and an average length, width, or diameter smaller than 500 nm. The binder or matrix material bonded to the platelets to form the nanocomposite material create a surface area greater than 500 m2/gm.
Angstron Materials leads the industry as the only advanced materials company to offer large quantities of both pristine graphene and oxidized graphene. Multi-layer graphene, both pristine and oxidized versions, are collectively referred to as nano graphene platelets (NGPs). NGPs offer improved performance properties including very high Young's modulus, strength and surface area, superior thermal and electrical conductivity, lower density and less weight. NGPs are also resistant to gas permeation. As a result, Angstron is able to work with companies to develop products for batteries, fuel cells, supercapacitors, light weight structural components as well as electromagnetic interference (EMI), radio frequency interference (RFI), electrostatic discharge (ESD), lightning strike and other functional and structural composite applications. In addition to its ability to provide sample materials and scale-up, Angstron partners with customers to help manufacturers identify optimal designs, experience with research and development to help manufacturers harness the advantages of nano compositions and manufacturing processes.
Available in a wide range of geometries, NGP products are easily surface functionalizable for polymer and common solvent applications and offer high loading potential for nanocomposite applications. Angstron combines real world technology to make next generation products in the aerospace, automotive, energy, marine, construction, electronics, medical, and telecommunications markets.

PolyOne Presents Wire and Cable Solutions for Fire Protection at Railway Conference
PolyOne Corporation, a premier global provider of specialized polymer materials, services and solutions, is sponsoring and presenting at the upcoming Sixth Annual Fire Protection of Rolling Stock conference. This event will take place in London, March 24-25, 2010.
Maryline Desseix, PolyOne LSFOH product manager, will present a technical paper at the conference that explains how to develop safe flame retardant solutions for railway cables in rolling stock applications while complying with regulations and meeting railway operators' and manufacturers' specifications. Cables and accessories in the railway industry are used in a variety of infrastructure and rolling stock applications, and cover underground, railways, subways, trams and mass rapid transit propulsion equipment.
"Fire protection is of paramount importance in the railway industry," said Desseix. "The vulnerability factor for railcars is high because elevated tracks and tunnels can make evacuation during a fire difficult and dangerous. While it is important that materials be flame retardant to withstand ignition and limit flame propagation, it is equally important to address other factors including smoke generation, toxicity, dripping, and corrosivity."
Fire safety management for rolling stock is becoming an increasingly complex issue due to constant changes in technical and regulatory environments. In addition to these changes, the development of new technologies and systems means that fire protection approaches must be constantly reviewed. Desseix's presentation will highlight how PolyOne's latest solutions and developments can help the wire and cable industry increase fire safety for rolling stock applications.
PolyOne Corporation, with 2008 annual revenues of $2.7 billion, is a premier provider of specialized polymer materials, services and solutions. Headquartered outside of Cleveland, Ohio USA, PolyOne has operations around the world.
STAEDTLER Manufactures the Ecologically Efficient WOPEX Pencil using KRAIBURG TPE Compounds
The STAEDTLER Group is Europe's largest manufacturer of felt-tip pens, erasers, wooden pencils, fineline leads for mechanical pencils, modeling clay and industrial plastiline. When designing WOPEX, its latest product innovation, the firm turned to the thermoplastic elastomers (TPEs) made by KRAIBURG TPE. Those compounds offer ideal bonding with the substrate in the STAEDTLER pencil and make for a solid grip with a pleasant touch. Over and above that, the highly transparent TPEs let STAEDTLER dye the material in any of a wide variety of shades - a real design advantage. This is also confirmed by prizes like the prestigious "Design Plus 2009" award, presented on the occasion of the "Ambiente" design fair in Frankfurt. Moreover, the KRAIBURG TPE compound is part of a sustainable production process. The basic material for WOPEX is a natural fiber laminate (or wood polymer material) containing seventy percent wood; the remainder comprises varying parts of plastics and additives. This make it possible to use the efficient co-extrusion process, offering lower energy costs and less waste than was the case in conventional pencil manufacture. The wood is used in its entirety. That is one of the reasons why this innovative pencil was recently also designated "Bio-Material of the Year 2009".
A part of eco-friendly WOPEX manufacture: TPE compounds from Waldkraiburg
The challenge faced by the WOPEX project team was to identify a compound that would bond with the wood polymer material. Holding true to the company's motto - "Custom-engineered TPE and more" - the specialists at KRAIBURG TPE worked in close cooperation with STAEDTLER to develop the ideal solution for the pencil's surface. The compounds ensure a comfortable, non-slip grip. The high degree of transparency makes it possible to add color in numerous variations, turning the TPEs used in WOPEX into an optical highlight in the metallic silver-blue finish.
The natural fiber laminate, joining the thermoplastic elastomers, makes for efficient manufacture in the co-extrusion process, entirely without solvents. The materials are plasticized at temperatures of from 130 to 180 degrees Celsius and are then fed to a specially engineered co-extrusion head. There the individual streams of resin are metered in the right quantities and delivered at the required relative positions. The advantages: Energy needs are trimmed and the number of steps in the process chain is reduced considerably when compared with conventional pencils. The wood used as the feedstock material is employed far more efficiently. In addition, that material consists exclusively of PEFC-certified wood (Program for the Endorsement of Forest Certification Schemes) originating in German forests managed for sustainability. This increases the amount of wood utilized in each tree and reduces scrap, which can be as much as eighty percent when manufacturing conventional wooden pencils.
"We assign top priority to developing products that let our customers launch sustainable manufacturing and, in so doing, promote the welfare of people and the environment," says Oliver Zintner, European Business Director at KRAIBURG TPE. "That is why we are all the more pleased to be part of an ecologically advanced production process like the one used to manufacture WOPEX."
