0 Comment

Calcium Carbonate has CaCO3 as its chemical formula. It is generally found in rocks like minerals, limestone and it’s the principle component of shells of sea animals like snails and also of pearls.

Calcium Carbonate Powder is taken into use in an extensive assortment of rubber applications like a detacktifying and extender agent. In other rubber usages, it can enhance stiffness or offer abrasion resistance. Some distinctive examples of CaCO3 usages in rubber industry comprise about 15 to 20% filling of chalk inside unplasticized polyvinyl chloride (uPVC) drain pipe and 5 to 15% filling of stearate coated marble or chalk in uPVC window outline. PVC cables also utilize calcium carbonate at fillings of up to 70 phr to enhance mechanical properties (elongation and tensile strength) and electrical chattels (volume resistivity). Polypropylene mixtures are frequently occupied with CaCO3 to upsurge rigidity, a prerequisite that is significant at high use temperatures.
