Uses

Widely used in the composite material (electronic components, packaging materials, high-performance rubber products, automotive housing, mold), paper, ceramics, building materials, rubber, plastics, paints, coatings, chemicals, welding, nylon, casting powder of metallurgy, as well as asbestos substitutes and other fields.

Functions

Used in plastics to improve the impact strength of products to enhance liquidity and improve the tensile strength, tensile strength and modulus of linear shrinkage.

Having a good reinforcement in the paint,  can enhance the toughness and durability of coatings, and can keep the paint surface and smooth with good gloss. And improved resistance to washing and weathering performance, and can reduce the paint and ink Oil Absorption and maintain basic, with corrosion resistance. You can get high-quality brightly colored paint, and with good leveling and anti-aging properties. The coating can be better mechanical strength, increased durability, enhanced adhesion and corrosion resistance.Also has good coverage, adhesion.

In the application of ceramic can increase the strength of the ceramic body and a ceramic product, reduce ceramic fragmentation and mottle glaze, glaze surface gloss increased, also can reduce fuel consumption (fuel saving 60%); for ceramic and glass manufacturing process of calcium oxide and oxide of silicon raw materials and metallurgical industry low temperature flux.
