LAMINATED FOAM FILM OR WEB

摘要

A foam laminate foil or web and process therefor. The laminate includes an unfoamed top layer containing an elastomer grafted styrene-acrylonitrile copolymer (ASA), grafted with polyfunctional acrylates and a chlorinated polyethylene (PEC) and/or a rubber-like ethylene-propylene mixed polymer (EPM) and/or a rubber-like terpolymer of ethylene, propylene and a diene, a closed pore polyolefin bottom layer with a bulk density of 30 kg/m3 to 700 kg/m3 which includes an ethylene homo- or copolymer, and an intermediate layer arranged between the bottom layer and the top layer and which acts as a coupling agent. The intermediate layer includes a low pressure polyethylene, an ethylene-vinyl ester copolymer and a rubber-like ethylene-propylene mixed polymer (EPM) and/or a rubber-like terpolymer of ethylene, propylene and a diene (EPDM).
