Two suppliers have come out with a new type of flexible, translucent, semicrystalline nylon based 100% on renewable sebacic acid from castor oil. Nylon 1010 was introduced at NPE in Chicago by DuPont Engineering Polymers, Wilmington, Del., as part of its Zytel RS (renewably sourced) line. It’s also a new product from Evonik Degussa Corp., High Performance Polymers, Parisppany, N.J. (Vestamid Terra DS). It is described as bridging the performance gap between nylon 12 and 1212 and nylons 6 and 66. It has some advantages in resistance to fuels and polar fluids and provides good contact clarity. (Evonik offers 1010 blends with even better translucence.) Properties and pricing are similar to nylon 11 or 12. Unreinforced grades can be used to extrude flexible tubing, such as for fuel lines. Reinforced grades could be used in handheld electronic devices.
Both firms also offer nylon 610—a new product for Evonik, but not for DuPont—which is derived 60% to 63% from sebacic acid from castor oil. Evonik describes nylon 610 as having properties between those of nylon 612 and nylons 6 and 66. DuPont says nylon 610 is priced similarly to 612. It is used mainly for filaments, though DuPont worked with Denso Corp. of Japan to develop a special reinforced grade for Denso’s car radiator end tank (photo). It meets requirements for exposure to high heat, road salt, and physical abuse.
