摘要: A weatherstrip for automotive and motor vehicle window glass comprises a glass contact layer overlying a base extrusion. The base extrusion is formed of a thermoplastic vulcanizate (TPV) comprising ethylene-propylene diene polymer (EPDM) and polypropylene. The glass contact layer is formed of a material composed predominantly of a thermoplastic polyolefin polymer and comprising a silicone-crosslinked thermoset polymer. The thermoset polymer may be the reaction product of a silane-grafted polyolefin and a silicone polymer.
