Precipitated Silica
Precipitated Silica Industry Applications
Silica for Tires
High-dispersion precipitated silica for tire treads, hoses, belts, seals, and technical rubber. It partially replaces carbon black to enable “green tire” performance with lower rolling resistance and better wet grip.

Highly Dispersible Silica for Tires
Purpose-
Reinforcing filler improving modulus, tensile strength, abrasion resistance, and dynamic properties
Industrial Rubber Silica
High performance precipitated silica for industrial rubber goods such as conveyor belts, hoses, gaskets, seals, rice rollers, and vibration damping parts. It is designed for easy mixing, high durability, and resistance to heat aging in demanding service conditions.
Our Standard Offering (Customizable to fit-for-Purpose)

Purpose
Reinforcing filler for mechanical rubber goods, improving tensile and tear strength, abrasion and cut resistance, and flex-fatigue life, while helping to control heat build-up and maintain good surface finish and dimensional stability.
Electronics / Semiconductor-Linked Silica
Specialty silica grades aimed at electronics and semiconductor-related uses such as polishing slurries and insulating/filler systems where purity and particle control matter.
Our Standard Offering (Customizable to fit-for-Purpose)
-
High-purity amorphous silica with controlled ionic and metallic impurities
-
Tunable particle size and distribution for uniform planarization and dispersion
-
Supports CMP slurries and advanced dielectric/filler formulations used around semiconductor and electronics manufacturing
Construction & Coatings Silica
Silica grades for dry-mix mortars, grouts, tile adhesives, sealants, and decorative/industrial coatings that tune rheology and microstructure.
Our Standard Offering (Customizable to fit-for-Purpose)
-
Enhances compressive and flexural strength, reduces shrinkage in mortars​
-
Acts as rheology modifier/matting aid in coatings, improving anti-settling and scrub resistance
-
Provides more uniform pore structure and smoother, more durable surfaces
