    • A novel laminate useful for seals particularly for vehicle window seals that are flexible, wear resistant and have a low coefficient of friction, is provided. The laminate comprises a rubber substrate and a polyolefin coating disposed on and adherent to the rubber substrate. The invention also provides novel methods of making laminates, particularly seals. Such method comprises the following steps: providing a rubber substrate; then applying a powdered crystalline polyolefin to the rubber substrate, in an amount sufficient to form a continuous layer when melted; and then melting the powdered crystalline polyolefin to form a continuous polyolefin coating disposed on and adherent to the rubber substrate. The invention also relates to seals comprising: a polyolefin rubber body; and a continuous coating of fused polyolefin disposed on and adherent to the rubber seal. Preferably the continuous coating of fused polyolefin is disposed in the glass run channel in the rubber body.
    • 提供了一种用于特别用于车辆窗口密封件的密封件的新型层压材料,其具有柔性,耐磨性和低摩擦系数。 层压板包括橡胶基材和布置在橡胶基材上并粘附在橡胶基材上的聚烯烃涂层。 本发明还提供了制造层压板,特别是密封件的新方法。 这种方法包括以下步骤:提供橡胶基材; 然后将粉末状结晶聚烯烃施加到橡胶基材上,其量足以在熔融时形成连续层; 然后熔化粉末状结晶聚烯烃以形成设置在橡胶基材上并粘合到橡胶基材上的连续聚烯烃涂层。 本发明还涉及密封件,其包括:聚烯烃橡胶体; 以及设置在橡胶密封件上并附着在橡胶密封件上的熔融聚烯烃的连续涂层。 优选地,熔融聚烯烃的连续涂层设置在橡胶体中的玻璃导槽中。
