Product Description

SN-4603, SN-4803, SN-4903, SN-1272 and SN-1872Special calcium carbonate for plastic are functionality fillers which our company is specialized in researching and developing according to the characteristics and process performance of plastic industry. They select high purity and high whiteness calcite as raw material. They are produced through the advanced technology of wet process and wed surface compound and the process of drying in static station and constant temperature for multi-sections and secondary depolymerization. Their particle size is not only super fine but average size is under 1um after grind in multi-sections and surface polishing treatment. Particle size distributes narrowly and shape is similar to sphericity, which will not occur abrasion to equipment and inner oil absorption., can reduce to absorb other unnecessary Additives in plastic process. These products are made from high purity and high whiteness calcite as raw material, so there is no toxin and taste and will not affect other additives. These products use large-scale slurry pool, and are treated equably, so the quality is stable, they are compatible with resin very well after surface is activated treatment.
