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 performance and arc resistance.

2. It can reduce the exothermic peak temperature of epoxy resin curing reaction, reduce the linear expansion coefficient and shrinkage of the cured product, so as to eliminate the internal stress of the cured product and prevent cracking.

3. Corrosion resistance: silicon powder is not easy to react with other substances, and has no chemical reaction with most acids and alkalis. Its particles are evenly covered on the surface of the object and have strong corrosion resistance.

4. The particle gradation is reasonable, which can reduce and eliminate sedimentation and stratification during use; It can enhance the tensile and compressive strength of the cured product, improve the wear resistance, increase the thermal conductivity of the cured product and increase the flame retardant performance.

5. The silicon powder treated with silane coupling agent has good wettability to various resins, good adsorption performance, easy mixing and no agglomeration.

6. Adding silicon powder into organic resin as filler can not only improve the properties of cured products, but also reduce the product cost.

After reading the above introduction, I hope it can help you know more about Chengdu silica fume.
