Calcium Carbonate For Plastic
Calcium Carbonate as an inorganic filler used in plastics for many years. Our Calcium Carbonate can increase the volume of plastic products, reduce costs, increase hardness and rigidity, reduce plastic shrinkage ratio and improve dimensional stability; improve the processing properties, increase heat resistance, improve plastic astigmatism, anti - abrasions nature of smoothness; at the same time, can increase impact strength in gaps and mixing performance.
