Heavy Calcium carbonate ordinary

Heavy Calcium carbonate ordinary filling materials adopts high purity, High Whiteness Calcium which can be widely used in all kinds polymer filling modified powder coatings, oiliness coatings to improve physical dynamo property, reduce product cost.

[Product property]

1. High Whiteness, Whiteness≥95
2. High purity, calcium content higher than 99.5%
3. oil absorption value (DOPvalue ) is low
4. Particle diameter distribution is average . Application: common calcium carbonate filling materials series product suitable for Polyvinyl chloride (PVC) soft and hard transparent products, such as profiles, pipes, fittings, plates, film, leather, corrugated tile etc., As well as PE, PP, coatings, paper making, chemical industry etc.
