The surface activation treatment has better interfacial compatibility than untreated powder, and is easy to disperse A special activation modification process controls viscosity in the case of high filling ratios in the field of encapsulants Material filling can be done without affecting the chemical properties Under the microscopic morphology, the edges and corners of the particles are passivated and relatively regular. It has better fluidity than conventional silica powder
The activated silica powder series products independently developed by Shengtian are made by surface treatment and fine processing of natural quartz. The main component is SiO2, the surface has been activated and modified, and epoxy resin, silicone resin has a good affinity, in the application of epoxy resin and silicone resin as the main body, to achieve the maximum degree of high filling effect without affecting the performance.

Applications
Rubber & Tire Industry
Reinforcing filler to improve tear resistance and durability.
Coatings & Inks
Anti-settling agent, rheology modifier, and matting agent.
Adhesives & Sealants
Thixotropic additive for sag resistance and bonding strength.
Pharmaceuticals & Cosmetics
Flow aid, desiccant, or carrier for controlled drug release.
Electronics & Energy
Dielectric filler, battery separator coating, and thermal interface materials.
Food & Packaging
Anti-caking agent and moisture absorber (food-grade approved).
Advantages Over Conventional Silica
✔ Tailored Surface Chemistry – Compatible with polar/non-polar systems. ✔ Multi-Functional – Combines reinforcement, adsorption, and rheology control. ✔ Eco-Friendly – Non-toxic and recyclable.
Why Choose Activated Silica Powder?
Versatile performance across industries.
Regulatory compliance – Meets USP, EP, and FDA standards (for specific grades).
Custom solutions – Adjustable surface treatment and particle size distribution.
For technical data or application support, consult the manufacturer.
