    High whiteness with great coverage and strong hiding powder coverage.
    Shiny bright,fine grain,good absorption speed.Basic acid resistance is excellent
    and extraction of moderate physical and chemical properties such as stability
    characteristics. Being a new type alternative to plastic, are non-toxic and
    tasteless. Also environment-friendly features as filler, it can replace some of

titanium dioxide, and all direct alternative lithopone. Lowers cost of production.

Performance: Plasticity, bonded, decentralized insulation, sintering, flame retardant, fire resistance,
adsorption, weather resistance, chemical stability.
