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 µm ) 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 . |
