Microfine Dolomite

Microfine Dolomite is natural form of calcium carbonate widely used in plastics, Paints and Rubber as a filler due to its high dispersibility, low oil absorption, higher finish impact strength, smooth surface finish easy processing and excellent the end products.

Effects on properties of Polymers

  • Increase in flexual modulus
