General Description
Precipitated Silica is a high-purity, synthetic amourphous silica produced under controlled conditions as a fine white free-flowing powder with consistent quality and performance. It is widely used in industries such as rubber, tires, footwear, adhesives, sealants, coatings, plastics, food, pharmaceuticals, and personal care, where it functions as a reinforcing agent, thickener, and absorber to improve strength, durability, viscosity control, surface finish, and overall product stability. Owing to its high surface area, controlled particle size, chemical inertness, and non-toxic nature, Precipitated Silica is an environmentally safe and reliable functional ingredient compliant with international quality standards.

Applications
Rubber:
Used as a reinforcing and performance-enhancing filler to improve strength, abrasion resistance, and durability of rubber products.
Oral Care:
Functions as a mild abrasive and thickener to aid effective cleaning, polishing, and texture control in oral care products.
Food:
Used as an anti-caking and flow-improving agent to maintain free-flowing properties and consistency in powdered food products.
Animal Feed:
Used as an anti-caking agent to improve flow and storage stability of feed, and as an inert carrier to ensure uniform dispersion and stability of vitamins and micronutrients.
