Product Description

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


High-purity molten ultra-fine silicon micro-powder: This product is processed by crystallization and ultra-fine processing after crystallized quartz sand is subjected to non-setting treatment. 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. Mainly used in plastic and electrical products, plastic sealing materials, silicon silicone rubber, epoxy castables, potting materials, silicone rubber and other chemical fields.

Modified ultrafine silicon micropowder: 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.
