PP Filler Masterbatch is compounded of high quality filler, polymer resin and other additive agents by twin-screw machine. PP Filler Masterbatch is a Polypropylene based master batch containing 75% ~ 80% of calcium carbonate. It is natural white with excellent dispersity. It is widely used in the plastic industry (blow film, blow molding, injection molding, wire drawing, bag molding, slip casting, dyeing, extrusion molding) to reduce the production cost and improve the character of final products.
