Calcium carbonate

Calcium carbonate is a carbonate mineral, has low cost, high chemical purity, the inertia big, not easy to chemical reaction, good thermal stability, high whiteness, low oil absorption rate, non-toxic, tasteless, odourless, good dispersion, etc.

Pinguan heavy calcium carbonate series products have good dispersibility, mobility, abrasion resistance, reinforcement, and the surface activity, good optical performance advantages. Widely used in papermaking industry, plastic industry in composite materials, all kinds of plastic pipes, profiles, plastic products, degradable plastics and wire and cable materials; Rubber tires, rubber products, seal products in the industry; The oily bottom paint coating industry, high-grade car paint, powder coating material, coating and other products of the filling material.

The main role

Paper industry: with increasing surface luster, whiteness, improvement the action such as paper smoothness.

Pieces of plastic composites industry: can obviously increase the plastic composites interface bonding strength and mechanical properties; In the plastic all kinds of plastic pipes, profiles, plastic products, used in degradable plastics, toughening and reinforcing, improve the luster, improvement the action such as quality.

Rubber industry: can increase products tensile, tensile, heat resistance, ageing resistance, tear resistance and other properties.

Coating industry: can increase the thickness of the coating, to improve the wear resistance of the coating and weatherability, and at the same time can improve powder coating powder rate and the spraying area, and it does not contain heavy metals, is the first selection of type of powder coating does not contain heavy metal filler.

Pinguan can provide the following chemical index and physical index of the whole series of products:

Calcium carbonate chemical indicators:
