K‘2010 Review Show Review At K’2010, with 222,000 visitors the world’s biggest trade fair for plastics and rubber, held in Düsseldorf every three years, the bioplastics industry strengthened its presence from October 27 to November 03. In our K-show preview we already presented a large number of the bioplastics related products and services. This review will round off our report. Renewably-Sourced TPE for Airbag Systems Joint development work between Takata-Petri of Aschaffenburg, Germany, and DuPont has resulted in the launch of a new grade of DuPont Hytrel ® RS, the industry’s first renewably-sourced thermoplastic elastomer for use in airbag systems. Replicating the technical properties of the standard grade of Hytrel used for such applications, including consistent physical properties over a wide range of temperatures, the material contains a minimum of 35 % renewable content by weight, derived from non-food biomass, thereby addressing auto manufacturers’ needs for sustainable solutions. The newly-developed grade of Hytrel RS for airbag systems constitutes one of the latest technological advances in the area of renewably-sourced, high performance polymers. It is based on a thermoplastic ether-ester elastomer (TPC-ET) with hard segments of polybutylene terephthalate and soft segments that contain a polyether derived from non-food biomass. In its finished, compounded form, as used in airbag systems, its renewablysourced content is at least 35 % by weight. Innovative Range of Plant-Based Plastics The international Roquette group, world leader in starch and starch-based derivatives, has joined the plastics market and launched GAÏALENE ® , a new range of plant-based plastics for converters and compounders. GAÏAHUB ® is one of Roquette’s major innovation programmes and since 2007 they have been grafting natural polymers to create thermoplastic plant resins. “Gaïalene‘s manufacturing process is based on 75 years of expertise in starch transformation and the synthesis of its derivatives; it is also supported by a fruitful partnership with SETUP PERFORMANCE, a polymer expert,“ says Jean-Bernard Leleu, Deputy CEO of Roquette. Gaïalene has around a dozen patents that protect Roquette‘s technological innovations. “Our Gaïalene resins contain over 50% plant based materials and are completely new. They are not the result of mixing or compounding; they are the product of genuine hemisynthesis which gives them their original properties,“ Jean-Bernard Leleu continues. The new plastics from Roquette are plant-based alternatives with an excellent cost/effectiveness. Gaïalene is targeting sustainable applications using common polyolefins, ABS, or more technical polymers. The Gaïalene range is different from other plant-based plastics because of its very specific characteristics such as shock resistance, softness, and easy colouring and compounding (mineral fibres, plant fibres, etc.). These qualities open new horizons in traditional plastics applications like packaging (bottles, film wrap, etc.), household appliances, automobile industry, interior design and more. Gaïalene resins can be easily formed and converted at a lower temperature (about 170°C) than traditional plastics using existing industry processes: injection moulding, blown film, extrusion blow molding, etc. It is also recyclable and complies with REACH. 10 bioplastics MAGAZINE [06/10] Vol. 6

K‘2010 Review High Performance Castor Oil-Based Polyamides Belgium-based Solvay announced its partnership with Mitsubishi Gas Chemical (MGC) on the development of high performance castor oil-based polyamides. The material is expected to be among the highest temperature bio-based polyamides in the industry with a heat deflection temperature of approximately 270°C for glass-filled compounds, according to Solvay. Green Propylene Industrial Unit Announced During K’2010 Braskem, the largest thermoplastic resin producer in the Americas announced the conclusion of the conceptual phase of the project to build a green propylene plant. In 2011, work will be concluded on the basic engineering studies and, once final approval is obtained, the project‘s installation will begin, with operational startup expected in the second half of 2013. The plant should require investment of around US0 million and have minimum green propylene production capacity of 30 kt/year. To produce green polypropylene, Braskem will adopt technology that has already been proven on an industrial scale and use as an input sugarcane ethanol, which is recognized as the world‘s best renewable energy source. The green polypropylene will have the same technical, processability and performance properties as polypropylene made using traditional production routes. The preliminary eco-efficiency study has shown very favorable results, given the benefits from the environmental advantages of green ethylene. The study was conducted in partnership with Fundação Espaço Eco and was based on conceptual engineering data. Each ton of green polypropylene produced captures and sequesters 2.3 t of CO 2 . Solvay and MGC are currently working together to develop an optimized manufacturing process for the new polymer. MGC said it has filed numerous patents to cover its extensive development work in resin composition, production, and applications. The multi-year development project will examine market viability, commercial scale-up, and capital planning. Mitsubishi Engineering Plastics, in turn, launched its own biobased resin called Reny ® SRH0101 (tentative name) at K’2010, a high heat-resistance polyamide for injection molding materials that was newly created by Mitsubishi Gas Chemical. Mitsubishi said they plan to expand the resin in various grades.
