As a kind of general-purpose plastic, PP possesses a good mechanical property and excellent resistance to chemical attack. So, now, it is widely used. In this article, a kind of decorating materials used in automobile and rubber powders were used to undertake a modification of PP. Besides, mechanical property was tested and SEM,TMA,TG technology were used to investigate some of the property of composites. We drew a conclusion that the composite with a ternary system consists of PP,POE and rubber powder got the best integrated performance.
