Polypropylene (PP) is a kind of semi-crystalline polymer, which has excellent mechanical properties and has been widely used.

PP Functional Modification

Blending modification refers to the blending of other plastics, rubber, or thermoplastic elastomers with PP and filling them into larger crystal spheres in PP to improve the toughness and low temperature brittleness of PP.

PP is a common plastic raw material and one of the commonly used modified raw materials. The modification methods can be divided into four kinds: filling modification, strengthening and toughening modification, blending modification and functional modification.
