Amorphous precipitated silica for rubber as reinforcement
 Silica is a white crystalline powder, it is more effective than carbon.First of all, it can reduce the friction between the tire deformation inside the molecule, thereby reducing the rolling resistance of tire,up to an average of about 30%, environmental protection and high efficiency. Second,it can reduce tire vibration, reduce tire noise. Now many branded tires have used the silicon material, the price is about twice of carbon rubber material. Such as Michelin XM1, EP100 green song, and so on. |
Our JS-185MP is micro pearl and has better dispersity and reinforment.
