No. 2:  It seemed that bioplastics came of age as a molding material at K2010. Their primary application for many years will remain throwaway packaging. But several producers introduced variants with engineering potential at the big German show. Leading the way were five producers with polyamides made from castor oil. DuPont showed 10 products made in part from renewable resources including corn (Sorona EP), castor oil (Zytel RS), and unidentified renewable resources (Hytrel RS and Biomaxx PTT). DSM also showed off a significant strategic emphasis on renewably sourced materials, including Arnitel Eco, a high-performance thermoplastic copolyester and Palapreg Eco, a bio-based thermoset molding compound. Compounder PolyOne exhibited a family of bio-related compounds and additives including GLS OnFlex BIO thermoplastic elastomers. Braskem announced plans at K 2010 to produce polypropylene from a sugar cane feedstock.
