High performance polyolefin blends for industrial pallets other articles and a process for the preparation thereof

摘要

A thermoplastic polyolefin blend comprising of a base polymer and up to 25% by wt of an ethylene propylene diene monomer (EPDM), the balance if any consisting of a conventional filler and/or a conventional compatibilizer or interfacial agent is disclosed. The blend of the present invention is prepared by extruding a base polymer with ethylene propylene diene monomer (EPDM) at a temperature in the range of from 150 to 230° C. The blends of the invention exhibit very high mechanical properties at moderate concentrations of EPDM and/or filler, and can be made into industrial pallets either by injection molding or by thermoforming.
