Application：
Rubber Application: Shoe industry, Tyre industry, Indusry rubber products,
The plastics industry .
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.
Industry 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.
