Low Oil Absorbing Calcite decomposes in acids and has a Mohs hardness of 3 and specific gravity ranging from 2.7 to 2.9. Calcite is widely used as a filler due to its high dispersibility, low oil absorption, higher impact strength, smooth surface finish, easy processing and excellent dimensional stability. Calcite is available in lump as well as powder form. Low Oil Absorbing Calcite is extensively used in plastics, paints and rubber industries.
