WEB EXCLUSIVE: In this month’s Starting Up section, we report on a new nylon 410, based on castor oil, from DSM of the Netherlands and Evansville, Ind. It boasts a melting point of 250 C (higher than biobased nylon 610) and very low moisture absorption. Late last month, Arkema of France (U.S. office in Philadelphia) and Toyobo of Japan also announced that they are jointly developing high-temperature nylons based on castor oil. The first new products will be two series of polyphalamides (PPAs) with melting points around 250 C and 315 C, very low moisture absorption, and biobased content up to 70%. They are aimed at LEDs and metal replacement in consumer electronics and automotive applications where requirements for heat resistance and dimensional stability have not previously allowed plastics to be used. Toyobo and Arkema will both make and market the resins. The new grades round out the Rilsan HT range of 70% biobased PPAs, introduced last year in flexible extrusion and blow molding grades and ductile injection grades. However, the previous grades has melting points only up to 260 C. Incidentally, another PPA based up to 50% on castor oil was introduced last year by Evonik Degussa (U.S. office in Parsippany, N.J.). Vestamid HTplus TGP3537. It is a nylon 10T (terephthalate) including heat stabilizer and 30% glass fiber. It boasts high heat resistance (suitable for LEDs), low water absorption, and a broad processing window. (800) 225-7788 • arkema.com (800) 367-4857 • degussa-hpp.com
