PP-TDPP toughened modified engineering plastic is a kind of engineering plastic material based on polypropylene (PP) and toughened by adding modifiers such as TDPP (cycloolefin copolymer). This material has the excellent basic properties of polypropylene and enhanced toughness and impact resistance. It is widely used in the fields of automobiles, electronics, home appliances, consumer goods, etc. PP-TDPP toughened modified engineering plastic has excellent processing performance. It has good fluidity and can perform well in common processing methods such as injection molding and extrusion. Due to its toughening characteristics, PP-TDPP is not easy to break or crack during processing, and has high molding stability.
