Ultrafine silica median particle size2~4
Ordinary crystalline ultrafine silicon micropowder: combined with resin and silica gel can enhance the tensile strength, making the product not easy to tear, not easy to age, not easy to corrode. The product is made from quartz sand through an ultra-fine process. It has a narrow particle size distribution, a large specific surface area, and good replenishment performance. Can be used in coatings, 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.
