Silica Material Portfolio
Compare crystalline silica powder, fused silica powder and sand, cristobalite, ultrafine silica and surface-treated silica for industrial applications.
PRODUCT FAMILIES
Start with the material family that matches your process, then compare grades, particle sizes, properties and applications.
Crystalline silica powders for coatings, silicone rubber and electronic packaging.
Low-expansion fused silica powders, sand and granules for casting, refractory and ceramics.
High-whiteness cristobalite flour, powder and sand for casting, coatings and engineered compounds.
Clean quartz raw material and refined particles for purity-sensitive industrial applications.
Refined translucent and porcelain-white quartz sand grades for casting, ceramics and refractory uses.
Precision quartz rods, plates and engineered quartz components for technical applications.
Crystalline silica powder for tile adhesive and grout formulations, with controlled grading for dry-mix workability, filler packing and consistent joint texture. Confirm grade-specific data with Changtong.
Natural-quartz-derived surface-treated powder for epoxy flooring formulations. Intended for controlled comparison of hydrophobic response, filler wetting, dispersion, oil absorption and viscosity build; final performance must be validated in the customer's resin and flooring system.
Natural-quartz-derived silica powder with hydrophobic surface treatment for evaluation in EV battery module encapsulation, sealing and insulation resin systems. Controlled particle-size options support moisture, dispersion and viscosity studies; final grade and acceptance limits must be matched to the customer’s resin and process.
Crystalline silica filler for electronic packaging and epoxy encapsulation, with a 2000–5000 mesh reference, whiteness ≥92, Mohs 7, good mobility and anti-overflow focus. Confirm the resin system and acceptance limits before sampling.
Crystalline silica filler for paint and coating formulations, covering 600–2500 mesh with whiteness ≥95 and a source-backed focus on oil absorption, dispersion, viscosity control, mobility and rub resistance. Confirm the target binder and grade before sampling.
Crystalline silica filler for silicone rubber compounds, covering 1000–3500 mesh with whiteness ≥95, Mohs 7, low moisture, electrical insulation and reinforcement as the approved application focus. Confirm the compound and cure process before sampling.
Active silica powder made from selected natural quartz through fine grinding, classification and hydrophobic surface activation. It is intended for polymer masterbatch, resin and specialty compound formulations where water repellency, low oil absorption, low viscosity build, high dispersion and resin compatibility are important. Final performance depends on the treatment level, resin polarity, loading and mixing conditions.
Silane-treated silica powder for industrial sealant and adhesive formulations. The treated mineral surface is designed to improve filler wetting and compatibility in selected organic binder systems, while controlled particle-size options support practical mixing. Confirm treatment chemistry and test requirements against the customer’s polymer and cure process.
Fine silica powder for precision ceramic bodies, technical glass batches and other silica-rich formulations. Controlled grinding, particle-size options and low-iron chemistry support clean mineral addition where batch consistency and appearance matter. Final grade should be matched to the customer’s firing or melting process.
Ultrafine crystalline silica powder in 1000–3000 mesh options for welding-electrode coating and welding-flux formulations. Controlled grinding, classification and low-moisture packing support fine blending and consistent raw-material handling. Final grade must be matched to the manufacturer’s complete coating or flux formulation.
Fine silica powder filler developed for epoxy and other electronic potting compounds. Controlled particle-size options, low moisture and consistent batch processing support stable mixing, reliable filling and dimensional control in encapsulation formulations. Final grade and acceptance limits should be matched to the customer’s resin system.
General-purpose 325 mesh crystalline silica powder for ceramics, refractories and mineral-filled industrial compounds. Controlled screening supports consistent dry blending and formulation. SiO₂ is maintained at 99.3–99.7%; confirm the required particle-size distribution and test method with your order.
