Product introductionWhite powder

 

Introduction:No heavy crystals, Reduce specific gravity and increase powder loading rate; Increase coverage, replace barium sulfate, reduce cost. It has the advantages of good dispersion, high whiteness and good optical properties

 

Rubber industry: Calcium carbonate is used in rubber products. the higher the absorption oil value, the better the wetting and reinforcing properties of rubber.

 

The plastics industry: Calcium carbonate is used in plastic products, reduce cost, improve stability, hardness and steeliness, improve the processing performance of plastics. Improve its heat resistance, It has obvious effects on improving heat resistance, astigmatism, abrasion resistance, smoothness, toughening of notch impact strength and viscosity flow in mixing process.

 

Coating industry: Calcium acid added to the coating, can be used as a whitening of high quality filler, improve the coating, paint glossiness, at the same time play a strengthening role.

 

Printing ink industry: Calcium carbonate is used in ink products, showing excellent dispersion, excellent gloss and hiding power, as well as excellent ink absorption and drying.

 

Application:Widely used in wire and cable, molding products, hard pipe, special-shaped pressure, floor tile, film, powder coating, synthetic resin, oil paint, emulsion paint, primer paint, shoes, tires, sponge, rubber paste, rubber lining, belt hose, toothpaste, cosmetics, acid neutralizer and other industries.
