Calcium Carbonate Characteristic
1.Identical grain size ,low oil absorption value.
2.To reduce the cost of products ; to make products have good foamed effect.
3.To enhance hardness,rigidity,size stability ,fire-retardantness,glossiness of products.
4.In rigid PVC products, it can accelerate gelation, enhance cold impact strength, eliminate plate out, and improve surface gloss.
