Material Notes:

Elastocon® STK40B is a black thermoplastic elastomer that has been developed for applications that require ultra soft rubber-like properties and a good surface finish. Elastocon® STK40B is well suited for consumer goods and industrial applications requiring non-slip/soft dry-touch ergonomics, sound and vibration dampening, improved impact resistance, and U.V. stability. Elastocon® STK40B can be overmolded to PC, ABS, PC/ABS, Acrylic, HIPS, copolyester, various grades of polyamide, and more.Information provided by Elastocon TPE Technologies, Inc.
