Active silica powder
- Product Usage:Active silicon micro powder product series: China ultra white silicon micro powder, silica powder for silicone rubber manufacturing, silicon micro powder for insulation casting of high-voltage electrical parts, silicon micro powder for high-voltage electrical casting, copper clad plate silicon micro powder. The characteristics of our company's activated silicon micro powder: it is made of imported organic coupling agent as the main raw material through composite activation. High activation rate, easy dispersion, and large amount of addition.
Description
Product features: simple ratio and good operation performance; The cured product has small shrinkage, stable size of molded parts, superior electrical performance, and good impact resistance and anti expansion performance. It is mainly used for insulation casting of electronic and electrical products.
Silica powder from AYAAON can effectively help customers to use silicon powder as filler to improve the electrical performance of products, while increasing the amount of addition, improving the mechanical processing performance and saving production costs. Provide customers with technical support and perfect after-sales service.
Our company has developed AYAAON GW series of activated silicon micro powder to meet the needs of different customers for activated silicon micro powder. Specializing in the provision of electronic, electrical, chemical, rubber, paint, water-based paint silicon powder products. Spherical fused silica powder for high heat resistance copper clad laminate: electronic grade ultra-fine silica powder with low expansion coefficient; Silica powder for rubber silicone rubber: silica powder for electronic ink UV ink: ultrafine silica powder for electronic ceramic ceramics: ultrafine silica powder for engineering plastics: ultrafine silica powder for electronic sealant powder filling glue; Filler silicon powder for adhesive: APG active silicon powder, modified active silicon powder for transformer power transformer.
The activated silicon micro powder is modified on the surface of silicon micro powder particles by silane composite materials through a unique process on the basis of ordinary crystalline silicon micro powder, so as to change the lipophilic property of the surface of silicon micro powder, effectively improve the adhesive force and interfacial hydrophobicity between resin and silicon micro powder, thus increasing the mechanical strength, elastic modulus, thermal aging performance and weather resistance of the cured product, More importantly, it can greatly improve the occurrence of partial free discharge of high-voltage electromechanical products.
Reactive silicon micro powder and resin curing agent react and cross link, which will not promote and retard the curing reaction of resin and curing agent system, and will not affect the casting process. Activated silicon powder is widely used in the casting of dry medium and high voltage electrical appliances, packaging of electronic materials and other industries.
