Active Silica Powder

Active silicon micropowder is developed from crystalline silicon micropowder through our proprietary process. By applying specialized modifiers to the particle surface, we effectively modify the original surface composition, significantly enhancing the adhesion between resin and silicon micropowder while improving interfacial hydrophobicity. This results in increased mechanical strength, elastic modulus, thermal aging resistance, and weather resistance of the cured product. Most notably, it substantially reduces localized free discharge phenomena in high-voltage electrical equipment.
It is a non-toxic, odorless, and pollution-free hydrophobic (lipophilic) high-purity white quartz silica micro-powder, characterized by its pristine white color, pure texture, and high transparency. It exhibits excellent flowability, superior dispersibility, outstanding anti-settling properties, good temperature resistance, acid and alkali corrosion resistance, moderate thermal conductivity, high insulation, low expansion, stable chemical properties, and high hardness.
The main purpose of surface treatment of silicon powder is to improve the performance of the filling system. It has the characteristics of chemical stability, acid and alkali resistance, large specific surface area, well developed pore, high surface activity, good dispersibility, low oil absorption, strong thickening, high temperature resistance, good electrical insulation, anti-UV, and no discoloration when mixed with silica gel or heated.
