Precipitated silica is a highly versatile inorganic chemical that is manufactured by neutralizing a solution of sodium silicate with sulfuric acid. The substance is a crystalline form of synthetic amorphous silicon dioxide. The chemical is used in various industries including rubber and plastics, oral health care, food processing, pharmaceuticals additive, and many more. This white, powdery material is used for numerous applications, including:
1. Adhesive
Precipitated silica is used to enhance bond strength and as a reinforcing and thickening agent. The dispersed silica particles within a liquid adhesive hardens fast when it is in contact with solid surface. It also serves as a free-flowing agent for spray dried resins.
2. Footwear
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 transparent materials. It also provides superior durability and resilience. The substance acts as white reinforcer facilitating manufacturing of colored end products.
3. Rubber
Precipitated silica is used in manufacturing of tires, industrial rubber, silicone rubber and footwear. Tires manufactured using the substance provide a great mileage and enhanced performance of the vehicle. Precipitated silica extends the shelf life for uncured rubber.
4. Conveyor Belts & Transmission belts:
Precipitated Silica is used to improve the tear strength due to its small particle size and complex aggregate structure. It imparts the highest degree of reinforcement to elastomer compounds. The substance is used to prevent from cracking and cut growth of Conveyor Belts and power transmission belts.
5. Pesticides
Precipitated silica is used as a carrier and diluent because in comparison with cheaper clays, it has high absorption, easier suspensibility, better compatibility with most toxicants and better stability. Even after extended storage under tropical condition.
