GMW16233

Description / Abstract: GMW16233, 6th Edition, May 2019 - Thermoplastic Elastomers - Styrenic, Exterior, Weatherable

Material Description. This specification covers the properties of black, heat stabilized, weatherable thermoplastic elastomers consisting of Polypropylene (PP) and Styrene/Ethylene/Butylene/Styrene (SEBS) rubber for exterior applications. These materials can be processed by extrusion and injection molding. These materials are bondable to other olefin-based materials. Materials approved to this specification shall meet part performance requirements for 2-shot bonding, if used in such applications.

Material types are delineated by hardness values. The types and corresponding hardnesses are defined in Appendix A, Table A1.

Symbols. The material abbreviation according to ISO 18064 is TPS-SEBS.

Applicability. Typical applications include exterior lace and closeouts.
