(1) Good insulation: Due to the high purity of silicon powder, low impurity content, stable performance, and excellent electrical insulation, the cured product has good insulation and arc resistance.

(2) It can reduce the exothermic peak temperature of the curing reaction of the epoxy resin, reduce the linear expansion coefficient and shrinkage rate of the cured product, thereby eliminating the internal stress of the cured product and preventing cracking.

(3) Corrosion resistance: Silica powder is not easy to react with other substances, and does not chemically react with most acids and alkalis. Its particles are uniformly covered on the surface of the object, and it has strong corrosion resistance.

(4) The particle gradation is reasonable, which can reduce and eliminate precipitation and delamination during use; it can increase the tensile and compressive strength of the cured product, increase the wear resistance, and increase the thermal conductivity of the cured product and increase the resistance. Combustion performance.

(5) Silica powder treated with silane coupling agent has good wettability to various resins, good adsorption performance, easy to mix, and no agglomeration.

(6) Silica powder is used as a filler and added to the organic resin, which not only improves the performance of the cured product, but also reduces the product cost.
