High lubricity, multi-layer polyolefin laminate
摘要:
The laminate of the invention comprises a sliding member of a resin composition and a Substrate layer of a thermoplastic olefin elastomer (A), and is obtained by co-extruding: the resin composition which is obtained by melt kneading a thermoplastic olefin elastomer (A), an ultra-high-molecular weight polyolefin (except a powder thereof having a particle diameter of 1 to 100 &mgr;m) having an intrinsic viscosity, as measured in a decalin solvent at 135° C., of 1 to 40 dl/g, an inorganic or organic filler powder, and optionally, a polyolefin resin, an organopolysiloxane, a fatty acid amide and a fluororubber in a twin-screw extruder, and the thermoplastic olefin elastomer (A). The laminate has excellent sliding properties with window glass and excellent abrasion resistance. Moreover, the laminate can be produced by a simple process because it requires no adhesive, and the laminate has great bonding strength between the substrate layer and the sliding member layer.
