A method with propylene copolymer as base resin, POE as toughing agent, PP-g-MAH as compatibilizer and TALC as filler was introduced to develop a new automobile dashboard material. The results showed that compatibilizer could improve the interfaoiaJ bonding, comparing with those not adding compatibilizer, the tensile strength and impact strength of the compound could be improved 20% - 30% , but the flowability was reduced.
