Application:  
Shoe industry, Tyre industry, Indusry rubber products, The plastics industry,Animal feed additive and Rice roller.
1.Shoe industry: Rubber outsoles reinforcing filler,the performance of reinforcing close to the carbon black,it can be used for light-colored rubberproducts,transparent appearance and excellent wear resistance.
2.Tyre industry: Reduce tire rolling resistance,increasing tire grip in the wetlands and icy ground.
3.Indusry 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.
4.The plastics industry: To improve plastic s toughness,strength,waterproof.  
5.Animal feed additive: To be as carrier, is not easy to agglomerate,excellent anti caking property, fluidity of the powder can enhance the liquidity of the production.  
6.Rice roller: Improve the wear resistance of rice roller.
