Calcium Carbonate in PVC

Calcium Carbonate in PVC

Calcium carbonate (CaCO3) is one of the fillers used in the PVC pipe production industry, which, in addition to reducing the total price, affects the mechanical characteristics, surface characteristics of the polyvinyl chloride pipe, elasticity, strength, shrinkage and many other properties of the product. Of course, the calcium carbonate used in the PVC pipe production industry must have a special granularity and be coated or coated calcium carbonate, Calcium carbonate improves the properties of polyvinyl chloride by increasing the hardness of the polymerized matrix and increases the resistance of the pipe by reducing the particle size. Calcium carbonate also improves compound performance by better dispersing the compounds in the PVC powder and homogenizing the polymer.
