Chemical formula: SiO2.
Molecular weight: 60.084.
CAS number: 7631-86-9.
EINECS number: 231-545-4.
Purity: 99.9%.
Particle size: 1um, 2.5um, 10um, 20um, 30um, 55um, 100 mesh, 20nm (can be customized produced according to customer requirements).
Appearance: White powder.
Characteristics: It has good dispersibility and dispersion stability. High reactivity, relatively low loose density of powder, easy to disperse and use. It exhibits high reflection characteristics for both ultraviolet and visible light. High purity, small particle size, uniform distribution, large specific surface area, high surface activity, high temperature resistance, low loose density. Has good dispersibility, suspension, and vibration liquefaction properties. Good insulation performance, high heat resistance, high moisture absorption, and high optical transparency. Good thixotropy, excellent reinforcement and thickening effects. After surface treatment, it has better hydrophilicity and oleophilicity.
Application:
1.Rubber, plastic, resin composite materials, papermaking additives, silicone rubber insulators, ink, PET, PP, PVC, etc.
2.Paint, coating, unsaturated polyester resin, layered resin and gel coat, HTV and RTV-2K silicone rubber, adhesive and sealant, printing ink, cable insulation adhesive and cable gel, etc.
3.Glass, quartz glass, water glass, optical fiber, electronic industry, optical instruments, handicrafts, cement, textile pulp, refractory materials, extinction industry, petroleum industry, etc.
4.Rubber modification, ceramic toughening sealant, adhesive modification, functional fiber additives, plastic modification, anti paint aging additives, anti caking agents, etc;
5.Ceramics, nano ceramics, and composite ceramic substrates;
6.Polymer: it can increase the thermal stability and aging resistance of polymer;
7.Flame retardant materials, coatings, grinding media, cosmetics and other products;
8.The toughness, strength, elongation, flexural performance, and resistance to UV and thermal aging of colored rubber products produced by adding a small amount of silica to solution polymerized styrene butadiene and chlorinated polyethylene all reach or exceed those of EPDM rubber;
9.After a small amount of silicon oxide is added to the traditional coating, the problems of poor suspension stability, poor thixotropy, poor aging resistance, and poor finish are well solved.
10.Used in cosmetics, functional ceramics, electronics, automobiles, water treatment and other fields. Due to its high specific surface area, it is very suitable for use as a catalyst carrier and various other adsorption materials.
