Let me talk aboutSilicon powderApplication in engineering plastics:

Mainly used in engineering plastic modification. The fibrous body structure and the longer length-to-diameter ratio have a good strengthening and toughening effect on plastics, which can replace glass fiber and greatly reduce production costs; improve the appearance of products, reduce shrinkage deformation rate, and improve dimensional stability; improve Heat distortion temperature, chemical resistance, corrosion resistance and mechanical processing performance; improve tensile strength, flexural strength, hardness, wear resistance, high temperature resistance and electrical insulation properties. At present, it is mainly used in the modification of plastic glass fiber such as PA, PP, PVC, POM, PBT, ABS and the filling of PE, PP, PVC, polyester, epoxy resin and phenolic resin to make the mechanical properties and mechanical processing properties of the products Significantly increased. (Note: Use silane coupling agent for surface active treatment effect).

Application in coatings: silicon micropowder material, surface hardness reaches Mohs level 7, filled in coatings and paints, and a reasonable combination with resin system can significantly increase the surface hardness of the product, improve scratch resistance and scrub resistance, suitable for industry Maintain the paint. It has a high temperature resistant softening point of 1700℃, which can significantly improve the high temperature resistance and fire resistance of the product, and is especially suitable for high temperature resistant coatings, paints, and fireproof coatings. The high-purity silica component gives it extremely strong chemical stability, which can significantly improve the acid and alkali resistance and corrosion resistance of the product. It is especially suitable for the production of anti-corrosion coatings and used in engineering construction with harsh environments. Good dispersion performance can improve the spraying effect of the coating. The unique shape and structure enable it to be well combined with the resin system. It is widely used in various industrial maintenance coatings such as high temperature resistant coatings, fire retardant coatings, insulating paints, anti-corrosion coatings, powder coatings, coil coatings, etc.

Application in rubber: ultra-fine can replace white carbon black, play a very good reinforcement effect, especially in silicone rubber, reduce production costs, improve the product's wear resistance, scratch resistance, high temperature resistance, corrosion, Insulation and other properties.
