SHOCK-ABSORBING PROPYLENE POLYMER COMPOSITE MOLDINGS

摘要

A shock-absorbing propylene polymer composite molding contains a. a layer with a thickness of from 0.5 to 10 mm which contains a propylene polymer having a melting point of from 130 DEG to 165 DEG C., b. an intermediate layer with a thickness of from 0.05 to 0.5 mm comprising a hot-melt adhesive based on an olefin copolymer having a melting point of from 90 DEG to 140 DEG C., c. a foam layer with a thickness of from 3 to 200 mm and a density of from 0.015 to 0.1 g/cm3 based on a propylene copolymer having a melting point of from 125 DEG to 155 DEG C., d. an intermediate layer with a thickness of from 0.05 to 0.5 mm comprising a hot-melt adhesive based on an olefin copolymer having a melting point of from 90 DEG to 140 DEG C., e. a layer with a thickness of from 0.5 to 10 mm which contains a propylene polymer having a melting point of from 130 DEG to 165 DEG C.
