Calcium Carbonate
It is identical grain size, low oil absorption value. It can reduce the cost of products: To make products have good foamed effect; To enhance hardness, rigidity, size stability, fire-retardantness, glossiness of products.
Usage
Injection mould, extrusion & injecting mould, PVC profile & pipe, FRP etc. Suitablefor the modification of PVC, PP, PE, ABS and HIPS. Fillers of Paint, Print ink, Plastic, Rubber, Adhesives, Pharmacy, Fodder, Paper-making, polyethylene(PE), polypropylene(PP), ABS, Building material, etc.
Characteristic
Identical grain size, low oil absorption value.
To reduce the cost of products; To make products have good foamed effect.
To enhance hardness, rigidity, size stability, fire-retardantness, glossiness of products.
In rigid PVC products, it can accelerate gelation, enhance cold impact strength, eliminate plate out, and improve surface gloss.
