The PP extrusion series products are specialized extrusion grade composite materials made by blending polypropylene (PP) as the matrix, surface activated talc powder as the main filler, and auxiliary agents for modification. They are widely used in the field of extrusion processing as general-purpose modified plastics. The material has excellent mechanical properties, dimensional stability, heat resistance, and weather resistance. The main processing method is extrusion molding, which is widely used in fields such as automotive internal and external water cutting, and has the advantages of low cost and easy processing.
