Many of these properties are highly dependent on the type and quantity of filler used in the compound. Silicone rubber is used in a number of applications where its unique properties provide a substantial benefit. It also improves adhesion in wire and fabric coat compounds and allows for rapid and easy processing, resulting in smooth finished surfaces in molded products. In industrial rubber ,precipitated silica confers superior strength and durability on industrial Rubber Belts and Rubber Hoses together with improved heat resistance and tear strength. Improves the abrasion resistance and stiffness.Precipitated Silica is used in Rubber Rollers and Rice Rollers for following reasons : Provides superior durability and resilience and improved modulus.Provides increased abrasion resistance and strength.Precipitated Silica is used for the following reasons in Railway Pads : Precipitated Silica is used to improve pigment dispersion and acts as a parting agent and as an absorbent to improve the flow and imparts a dry feel to the compound. Precipitated Silica is used to prevent from cracking and cut growth of Conveyor Belts and power transmission belts. It imparts the highest degree of reinforcement to elastomer compounds. Precipitated Silica is used to improve the tear strength due to its small particle size and complex aggregate structure. The EVA grade can be incorporated as it imparts good abrasion & modulus properties.īecause Precipitated Silica is white it allows the formulator to produce either colored or translucent nonmarking soles.Precipitated Silica provides superior durability and resilience while improving compound stiffness for all types of rubber soled footwear. We have recently introduced EVA grade for EVA footwear market. Provides superior durability and resilience and improved modulus.Īcts as white reinforcer facilitating manufacturing of colored end products. Precipitated silica is used in shoe soles for its resistance to wear and to tearing ,its non-scuffing characteristics and to obtain compounds with light color or even transperant materials. Serves as a free flowing agent for spray dried resins It prevents excessive penetration of adhesive into porous adherents.It improves flow control and heat resistance of hot melts in application. Supersil Silica prevents resin separation and the settling of pigments and heavy fillers. To adjust rheology and provide reinforcement. Supersil Silica provides thixotropy, reinforcement and promotes adhesion as well as serves as extenders, therefore it raises quality and lowers cost. In both natural and synthetic rubber based adhesive. The dispersed silica particles within a liquid adhesive hardens fast when it is in contact with solid surface. Supersil precipitated silica is useful to enhance bond strength and as a reinforcing and thickening agent. Other Suggestive Applications of Percipitated Silica
