Usage:
Injection mould, extrusion & injecting mould, PVC profile & pipe, FRP etc.Suitable for 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:
l Identical grain size , low oil absorption value.
l To reduce the cost of products ; to make products have good foamed effect.
l To enhance hardness, rigidity, size stability , fire-retardantness, glossiness of products.
l In rigid PVC products, it can accelerate gelation, enhance cold impact strength, eliminate plate out, and improve surface gloss.
