Calcite is a natural form of Calcium Carbonate which is widely used in plastics as a filler due to its high dispersibility, low oil absorption, high impact resistance, smooth surface finish, easy processing and excellent dimensional stability.
Applications of Calcite Powder
- PP compounding for furniture, automobile and home appliances.
- PVC Cable compounding, LDPE compounding, antifabrilliant masterbatches and other additive masterbatches, SMC & DMC, paper coating and powder coating.
