1, Instroduction: a,) Filler masterbatch is made of high quality calcium carbonate and other special additives after extrusion molding from high performance twin-screw machine. b,) widely used for polyolefin material in the process of extrusion, injection, and blowing. c,) when it is put into use, it can reduce material cost, and improve the character of final products.

2, Product characteristics: a,) Improves the anti-heating, rigidity and tightness property. b,) Removes the surface light from plastic products, to get sub-light. c,) Improves the surface antifriction and anti-slip property of plastic products. d,) Reduces shrinkage ratio of final products to improve size stability. e,)Reduces fire heating quantity of plastic product to reduce second pollution. f,) Improves surface printing property of plastic to reduce needed electric current under surface corona process. g,) Improves heat-conduction property of plastic material to reduce molding period. h,) Reduces the application ratio of white color masterbatch.
