Product Description

High-purity molten ultrafine silica powder: Mainly used in molding materials for electronic and electrical products, silicone rubber, epoxy castables, potting materials, silicone rubber and other chemical fields. This product is made by crystallized quartz sand after being subjected to non-setting treatment and then pulverized and superfine. It has light specific gravity (2.2~2.40/cm3), small linear thermal expansion coefficient, low stress, low radioactivity, excellent electrical properties and physical and chemical properties.

Modified ultrafine silica powder: This product is activated by a coupling agent on the basis of ordinary ultrafine silicon micropowder. It is easy to disperse with silicone rubber, rubber and other rubber compounds. It has excellent mixing, calendering and extrusion properties, and can improve the strength of the product. It can improve the processing performance of the product by replacing some of the white carbon black, which can greatly reduce the cost, especially suitable for Rubber products such as rubber rollers, hoses, wires and insulating sheaths, and silicone rubber products.

Ordinary crystalline ultrafine silica powder: This product is processed by quartz sand through ultra-fine process. It has narrow particle size distribution, large specific surface area, good waiting performance, good dispersion leveling and good suspension stability. It can enhance tensile strength, tear resistance, anti-aging and acid and alkali resistance by combining with resin and silica gel. Mainly used in coatings, rubber, engineering plastics, adhesives, precision casting, ceramics, refractory materials, electrical industry and epoxy resin.
