    • A polymer laminate produced by crosshead extrusion suitable for wear resistant applications such as a vehile glass run channel comprises a layer of a weather resistant rubber such as an ethylene-propylenediene (EPDM) rubber and a layer of a wear resistant thermoplastic such as polypropylene. The laminate is passed through an oven at an elevated temperature sufficient to cure the EPDM rubber, for example, at about 375.degree. F., with ambient temperature cooling fluid being blown over the exposed surface of the polypropylene thermoplastic. The interior polypropylene surface or interface is heated by the EPDM rubber which is at a high temperature as a result of the heat of extrusion and heat generated by cure thereof. As a result, the polypropylene interior surface or interface melts and causes it to flow and form a mechanical bond with the EPDM rubber while the exposed surface as well as a substantial portion of the polypropylene is kept from melting by the cooling fluid. The EPDM rubber can be extruded in the form of a channel having a longitudinal web which supports and is bonded to the laminated polypropylene wear strip to form a glass run channel.
    • 通过十字头挤出制造的聚合物层压材料,其适用于诸如车辆玻璃运行通道的耐磨应用,包括耐候橡胶层,例如乙烯 - 丙烯二烯(EPDM)橡胶层和耐磨热塑性层如聚丙烯层。 层压板在高温下通过烘箱,足以使EPDM橡胶固化,例如在约375°F,环境温度下冷却流体吹过聚丙烯热塑性塑料的暴露表面。 内部聚丙烯表面或界面被作为挤出热和其固化产生的热量的高温下的EPDM橡胶加热。 结果,聚丙烯内表面或界面熔化并使其流动并与EPDM橡胶形成机械结合,同时暴露的表面以及大部分聚丙烯不被冷却流体熔化。 EPDM橡胶可以以具有纵向腹板的通道的形式挤出,所述纵向腹板支撑并结合到层压的聚丙烯耐磨条上以形成玻璃运行通道。
