Ultrafine silicon powder

Superfine silicon powder is a kind of powder material made by special production process, which is specially used in industries such as silicone rubber, paint, coating, refractory and other chemical products. The utility model has the advantages of fine particle size, narrow size distribution, large specific surface area, not easy subsidence, and certain reinforcing effect, etc. the utility model has excellent effect on improving and improving the performance of the products and reducing the cost. The company may also be based on the needs of users to modify the powder, processing superfine silica powder.

Ultrafine silicon powder is widely used, such as silicone rubber, engineering plastics, adhesives, paints, coatings, dental materials, rubber tires, precision ceramics, refractories and so on.
