GMW15813

Description / Abstract: GMW15813, 3rd Edition, May 2017 - Thermoplastic Elastomers – Polyolefinic, Fully Crosslinked, General Purpose, Underhood

Material Description. This specification covers the properties of black and natural, general purpose, heat stabilized, thermoplastic vulcanizates (TPV) containing fully crosslinked Ethylene-Propylene-Diene Monomer (EPDM) elastomer particles dispersed in a continuous Polypropylene (PP) matrix. These materials can be processed by extrusion, injection, and blow molding. Material Types are delineated by hardness values. The types and corresponding hardnesses available are identified in Appendix A, Table A1.

Symbols. The material abbreviation according to ISO 18064 is TPV-(EPDM+PP).

Applicability. Typical applications include the following: mats, seals, gaskets, air ducts, Constant Velocity Joint (CVJ) boots, covers, grommets, and other parts where softness and conformity are needed.
