Fine Granular Silica Dioxide 


The Silica Dioxide Powder, Granular or Micro pearl form, Soluble in caustic alkali and hydrofluoric acid, insoluble in acids, water and various solvents. Resistance to high temperature, no combustion, good insulation properties
Shoe Industry: Rubber outsoles reinforcing filler,  the performance of reinforcing close to the carbon black, it can be used for light-colored rubber products, transparent appearance and excellent wear resistance 

Tyre Industry:  Reduce tire rolling resistance, increasing tire grip in the wetlands and icy ground.

Industrial rubber products: Applied to the rice roller, hoses, rubber rollers, belts, oil seals, etc., can improve  tear resistance, abrasion resistance, and extend the life of the products 

The plastics industry: To improve plastic’s toughness, strength, waterproof
