Calcium Carbonate for PVC Pipes :

Calcium carbonate powder is one of the most popular and essential mineral fillers used in the plastic industry for various purposes. As an important element in plastic compounds, CaCO3 helps decrease surface energy and provides opacity and surface gloss, which improves the surface finish of the products. Calcium carbonate improves the basic properties of polyvinyl chloride or PVC by adding stiffness to the polymer matrix and improving impact resistance as particle sizes become smaller. Calcium carbonate also improves the compounding performance of the PVC pipes by helping disperse various ingredients into the PVC powder blend and improves processing by making polymer flow more homogenous.

Magnesium Silicate (Talc) for PVC Pipes :

Used to increase stiffness and impact balance in PVC Pipes.
