Meta Description: Precipitated silica (white carbon black) delivers reinforcement, thixotropy and matting performance. Widely applied in rubber products, coatings, silicone sealants and agro-chemical formulations.
Our factory supplies high-quality precipitated silica (white carbon black), an amorphous hydrated silica powder manufactured by controlled precipitation process. In 2026, many rubber manufacturers, coating formulators and chemical processors adopt this multi-purpose inorganic filler. Featuring high porosity and adjustable BET specific surface area, it improves mechanical strength, rheology control and surface performance of end-products . Strict precipitation, filtering and drying procedures are adopted to keep stable batch-to-batch quality for global industrial customers across multiple sectors .
Precipitated silica possesses abundant micro-porous structure and high surface activity. When mixed with rubber or silicone materials, it builds stable interfacial bonding with polymer molecular chains. Test data shows that qualified reinforcing-grade silica can increase rubber tensile strength by more than 40 % and greatly boost tear resistance and abrasion performance. It helps extend service life of rubber parts such as seals, hoses and shoe soles under long-time mechanical friction.
This silica material brings obvious thixotropic effect in liquid systems. Under stirring or shearing force, the system turns into good fluidity; while at static state, viscosity rises rapidly to prevent pigment settlement and sagging. This property makes it ideal for paints, inks and sealant production, optimizing construction performance and reducing finished-product defects for coating factories. Precipitated silica can match diverse formula requirements through different surface-treated grades.
Properly graded white carbon black serves as an efficient matting agent for water-based and solvent-borne coatings. It creates soft matte surface without heavy gloss flare. Optimized particle-size distribution supports uniform dispersion inside resin matrix, avoiding agglomeration or grainy surface on final coating films.
Precipitated silica shows stable chemical property, insoluble in water and most common acid solutions except hydrofluoric acid. Non-toxic and non-combustible, selected grades can meet relevant safety standards for indirect-contact scenarios. It keeps stable under normal high-temperature processing conditions and will not decompose to release harmful substances during production.
As a core reinforcing filler, precipitated silica is widely used for green-tire tread compounds, industrial rubber belts, sealing gaskets and footwear rubber soles. It improves wet-skid resistance and lowers rolling resistance for tire formulas, and enhances wear-resistance of general rubber goods.
In coating and ink industry, it works as matting agent, anti-settling and thickening additive. It fits architectural water-borne paint, industrial protective coatings, powder coatings and printing ink systems, improving scratch-resistance and surface texture of coated objects.
Surface-modified precipitated silica is applied in sealant and adhesive production. It adjusts paste viscosity, prevents sagging during extrusion construction, and optimizes mechanical property after curing for construction-grade sealing materials.
Special-mesh silica can act as anti-caking carrier for agro-chemical powders and granules. It also finds uses in battery separator materials and detergent auxiliary fields, supporting diversified downstream industrial processing demands.
Precipitated silica is produced via wet-precipitation route, widely adopted for rubber reinforcement, coating matting and agro-carrier applications with high cost-performance. Fumed silica is manufactured under high-temperature gas-phase hydrolysis, more focused on high-end sealant and electronic material scenarios. Customers may select suitable grades according to their formula targets.
Yes. Proper high-dispersion grades can be mixed into water-based paint under sufficient high-speed stirring. Formulators should adjust adding proportion and grinding procedure to achieve expected matting or anti-settling results.
We support customized indexes including BET surface area, oil-absorption value and particle-size distribution. We can develop target-oriented silica grades based on customer formula test feedback, and supply TDS, MSDS and batch inspection reports for export shipment.
As global rubber, coating and fine-chemical industries keep upgrading formula standards, high-consistency precipitated silica becomes critical functional inorganic filler. Our production strictly controls precipitation reaction, filtering, drying and milling processes, monitoring key indexes for each batch to avoid large batch difference.
