developments range from automotive trim, weather stripping and gasketing to medical, flooring, wire/cable, and lawn/garden applications. Radici launched new Radilon D nylon 610, made from up to 60% sebacic acid from castor oil. It can compete with nylons 11 and 12 because of its improved thermal stability. Radici plans to release new long-chain nylons, including 100% biobased grades, in the next year. NatureWorks LLC and Altuglas International Resins featured the latter's new Plexiglas Rnew acrylic alloys incorporating 25% to 60% of NatureWorks' Ingeo PLA (plexiglas.com/rnew). They are said to offer some key improvements over straight PMMA (see Close Up in April). Research scientist Bob Barsotti at Arkema Group, Altuglas' parent company, cited significantly enhanced melt flow and chemical and impact resistance. Initially, Altuglas is targeting point-of-purchase displays and retail and outdoor signage. Frank Diodato, business man- ager of durables at NatureWorks (natureworksllc.com), sees application possibilities where typical PMMA cannot be used and the ability to compete with engineered resins in small and large appliances, housewares and other consumer durables, optical and medical products, building and construction, and automotive components. SABIC Innovative Plastics (sabic-ip.com) showcased what's said to be the first use of PCR material on heavy-duty trucks. SABIC's Valox iQ PBT, which is based partly on chemicals from depolymerized PET water bottles, is used in the brackets of the side air-deflection system for all seven models of the 2012 Volvo heavy-duty truck platform. SABIC also featured the new Canon Electronics scanner, which utilizes Xenoy iQ ENH PC/PBT, in which the PBT portion also has PET-derived PCR content. Styrolution (styrolution.com) launched what is claimed to be the first post-consumer recycled line of PS resins. Three grades, each with 25% PCR content, featured in the new Styrolution PCR line are injection molding grades PCR3125 (based on a 3100 GPPS) and PCR5625 (based on a 5600 HIPS); as well as extrusion grade PCR6225 (based on a 6200 HIPS). NEWS IN STYRENICS Styrolution also featured a new, cost-effective HIPS for food packaging. PS6220 is designed to be blended with GPPS to cus- tomize toughness and stiffness. It also simplifies extrusion, since its high gloss can eliminate the need for a coextruded gloss layer. New BX11012, the latest addition to Styrolution's Luran S ASA weatherable polymers, is formulated for low-gloss extru- sion applications that require higher flow than typical extrusion- grade ASA. Excellent impact strength and weather resistance are cited, suiting it to decking, fencing, and siding. TN 100306, Styrolution's newest Terluran ABS grade, is for- mulated for a Vicat temperature of 102 C for applications requir- ing higher heat resistance than most general-purpose ABS can handle. It's for auto interior door trim, consoles, and seat trim as well as exterior applications such as pillar garnishes and mirrors. Over 80 applications have already been developed using Teknor Apex's new Biovinyl compounds with a non-phthalate, biobased plasticizer. Potential uses are very broad, from con- sumer products, automotive, and medical parts to flooring, building and construction and lawn and garden. OTHER NEWS After two major acquisitions of the PET businesses of Eastman Chemical and Wellman, DAK Americas is developing a new portfolio for key markets, including carbonated soft drinks, hot-fill, water bottles and thermoforming. New product develop- ments under way include new bottle resins with up to 15% PCR content. DAK (dakamericas.com) also is developing extrusion blow molding grades of PET that have very high I.V. but maintain tensile and impact properties in order to compete with HDPE or multilayer HDPE/PP handleware in large detergent, personal- care, and juice bottles. DAK plans to test market PET resins with biobased content in the next two months. PolyOne showcased a new and reportedly unique, UL-certi- fied Geon rigid vinyl extrusion grade for electrical applications. It's the result of the company's work with sheet extruder Walton Plastics (Walton Hills, Ohio) and its customer, Midwest Plastic Fabricators (Aurora, Ohio). They were looking for rigid vinyl sheet to replace steel in outdoor electrical boxes such as control cabinets, junction boxes, and radio-frequency meters. The final formulation met requirements for processability, flame retar- dancy, weatherability, and water-penetration resistance, as well as UL 746C(f1) certification. SABIC Innovative Plastics launched four new additions to its Lexan PC portfolio. Lexan CFR (clear FR) copolymer for con- sumer electronics and appliances is a halogen-free grade that meets UL 94V-0 down to 1.0 mm thickness and UL 94-5VA at 3.0 mm. Three new Lexan LUX grades—2110T, 2010T, and 2910T— Continued on p. 61... PLASTICS TECHNOLOGY MAY 2012 45
