Precipitated Silica has become key filler for the tire industry due to its properties and performance. Precipitated silica in tire improves physical & dynamic properties such as tensile strength, abrasion resistance, tear resistance, wet grip etc. Silica is perceived by the tire industry as a material which can address the environment challenges associated with the tire production, and can replace carbon black in the tires. PPsilica is more environment friendly material as it requires lesser energy as compared to the conventional silica production methods, and uses a waste as base material for silica. Brisil produces Highly Dispersible Silica and Conventional Silica for Tires Application. Highly Dispersible Silica for Tires Highly Dispersible Silica is used in tires due its better dispersibility making it better reinforcing filler in tires. Good dispersion allows a greater filler contact area and a better homogeneity of the filler distribution within the compound. It also improves abrasive resistance and toughness of the tires due its abrasive nature and tensile strength. Globally, all major tire companies are looking to increase silica content in tires to improve the tire performance and reduce carbon black content. We Have Highly Dispersible Silica is best suitable for energy efficient green tires. The highly dispersible silica in tires results in Improved Process-ability. Better Tensile Strength. Improved Tear Resistance. Better Abrasion Resistance. Better Hardness.
Precipitated silica While carbon black, chemistry name "silicon dioxide" , main ingredient "sio2", similar to carbon black in the application , appearance showed white , highly dispersed , amorphous powder or flocculent powder. Main application: White carbon black is widely used as reinforcing agent for rubber and plastic , thickening agent for ink , additives for coating , and paint , flatting agent for leather , dispersing agents for insecticides , fillers for manufacturing papers , additives for resin , fillers for insulating and thermal insulation materials . Meanwhile , it is also used as open agent for polyethylene film and carriers, anti caking agent for food , pesticide and medicine. Package: 20kg or 10kg/ woven bag Package: 20kg or 10kg/ woven bag
Precipitated silica is an amorphous form of silica (silicon dioxide, SiO2) it is a white, powdery material. Precipitated silica is produced by precipitation from a solution containing silicate salts. ... Among them, precipitated silica has the greatest commercial significance.
Hengcheng's micro pearl silica is made from sulfuric acid and sodium silicate. By using the pressure spray drying technology, it provides our customers with non- dusting micro pearl silica that is denser than powder and easier to handle. We offer several packaging options. These include paper bags and big bags, on plastic or wood pallets, and in bulk in specially lined containers. This enables us to deliver anywhere in the world and according to customer needs and preferences.
Available for Rubber, Tyre, paint, pesticides, detergent etc also avalable Pharma and food grade
