Superfine silica powderIt is developed by Lianyungang Oster Silicon Powder Co., Ltd. for chemical products that require ultra-fine fillers such as silicone rubber, coatings, and refractory materials. It has the characteristics of reasonable ordering, controllable particle size distribution, and not easy to settle, and has excellent effects on improving and enhancing product performance and reducing costs. The company can also modify the powder and process ultra-fine active silicon powder according to user needs.

Superfine silicon powder is widely used in silicone rubber, plastics, coatings, dental materials, rubber tires, precision ceramics, refractory materials, etc. Good insulation performance: Due to the high purity of silicon powder, low impurity content, stable performance, and excellent electrical insulation performance, the cured material has good insulation and arc resistance. Epoxy resin can reduce the exothermic peak temperature of the curing reaction, reduce the linear expansion coefficient and shrinkage rate of the cured product, thereby eliminating the internal stress of the cured product and preventing cracking.

Corrosion resistance: Silicon powder is not easy to react with other substances. Most acids and alkalis do not react chemically. The particles evenly cover the surface of the object, which has strong corrosion resistance. It can improve the tensile and compressive strength, abrasion resistance, thermal conductivity and flame resistance of the cured material, and increase the heat transfer coefficient of the cured material. Silicon powder treated with silane coupling agent has the characteristics of good wettability, adsorption, easy mixing and no agglomeration. The addition of silicon powder to the organic resin not only improves the performance of the cured product, but also reduces the cost of the product.

The above is a small series, to give you a brief introduction to the functions of ultra-fine silicon powder, you can briefly understand. The content is for your reference only, you can contact our manufacturer if you want to know about it.
