Silicon Dioxide (SiO₂), commonly known as silica, is a high-hardness, chemically stable inorganic non-metallic material refined from natural quartz ore through crushing, purification and ultra-fine grinding. As a versatile functional filler and additive, it is widely used in architectural coatings, rubber and plastics, adhesives, electronic materials, daily chemicals and industrial precision polishing. It features core advantages of high purity, high whiteness, excellent insulation, wear resistance, stable chemical performance and outstanding cost performance.
Natural quartz ore is processed through simple crushing, conventional grinding and screening without deep purification and surface modification. With low production cost and general purity, it is suitable for ordinary concrete filling, low-grade refractory raw materials, common abrasive materials and cost-prioritized basic industrial scenarios.
Adopt precise processes including ore washing desanding, magnetic iron removal, high-temperature purification, airflow ultra-fine grinding and surface modification. Mineral waste residues can be recycled for construction backfill to realize green cyclic production. Finished high-purity silicon dioxide features high SiO₂ content, low impurity content, uniform particle size and good dispersion stability, meeting strict standards for high-end coatings, silicone rubber sealants, electronic insulation materials, cosmetic additives and food-grade anti-caking agents.
Free of heavy metals, radioactive substances and harmful chemical residues, conform to EU REACH, RoHS and national food, daily chemical and building material safety standards. Non-toxic and harmless, fully adaptable to indoor environment, food contact and cosmetic grade applications.
With excellent anti-ultraviolet and anti-aging performance, it will not powder, discolor or deteriorate after long-term outdoor and high-temperature use. Physical and chemical indicators remain stable under high temperature, humidity and cold-hot alternating environments.
Extremely high chemical inertness, stable in wide pH range, resistant to weak acid and weak alkali corrosion. Compatible with cement, resin, emulsion and polymer systems without chemical deterioration, suitable for various anti-corrosion and insulating systems.
Uniform microscopic particle structure with high hardness and stable refractive index. It can significantly improve wear resistance, scratch resistance, tensile strength and dimensional stability of coatings and rubber products, with excellent anti-settling and matting effects.
Ultra-fine uniform powder, not easy to agglomerate and can be quickly dispersed in water-based and solvent-based systems. Adaptable to coating mixing, rubber kneading, plastic extrusion, adhesive blending and other processing operations.
Formal manufacturers adopt standardized ISO quality control system, strictly control SiO₂ purity, whiteness, fineness and moisture content of each batch, effectively avoid poor reinforcement, coating sagging and product defects caused by raw material instability.
Interior and exterior wall latex paint, matte coating: adjust gloss, improve scratch resistance and anti-settling performance;Waterproof mortar and architectural putty: enhance compactness, improve weather resistance and structural stability.
Silicone rubber, rubber accessories: serve as reinforcing filler to improve elasticity and wear resistance;Structural adhesive, sealant: increase thixotropy, prevent sagging and improve bonding strength.
Electronic packaging materials, insulating fillers: excellent insulation and low thermal expansion;Cosmetic powder and food additives: smooth texture, anti-caking, safe and stable.
