High quality precipitated white carbon black (silica) as raw materials for ultra-fine processing to achieve micron particle size, close to the fumed silica in nature. Due to the advanced equipment and technology, product particle size distribution is very narrow. Uniform particle size, so that the product has a high specific surface area and difficult to obtain good reinforcement and dispersion. For high-temperature plastic, silicone rubber, to improve their tear strength. So, can partially replace fumed silica, to reduce costs, it is a better choice.
Applications:
Precipitated silica is mainly applied to silicone rubber, silicone rubber, intermediates, plastic mold, plastic glass, but also for paints, inks, tires, shoe soles, paints, cosmetics, textiles, cables and other industrial rubber products industry, but also as carriers or thickeners used in pesticides, fire extinguishing agents and advanced toothpaste paint and other fields.

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.
