Fumed silica and can be referred to as hydrated silica, superfine white amorphous powder, inorganic silicon compounds with high dispersion, good stability, high temperature resistant, light characteristics, purpose and function of fumed silica is available in many fields such as rubber, plastics, printing ink, dye application.
1.In the application of tires: fumed silica is second only to carbon black reinforcing materials, the largest use is in the field of rubber, accounting for more than 80% of its consumption, fumed silica can improve the physical properties of rubber, reduce rolling resistance. It makes up for the defects of carbon black in the field of white and color, and is the best material for producing green tires. Instead of carbon black, the tear strength and tear resistance can be enhanced, and the anti-cutting and anti-tearing performance can be improved when it is used in the tread.
2.Application in coatings: fumed silica in coatings can be used as rheological additives, anti-settling agent, dispersing agent, matting agent, etc., play the role of thickening, anti-settling, extinction, etc., while the coating weather resistance, anti-aging, ultraviolet absorption and other capabilities to improve
3.In the application of plastic: adding fumed silica in plastic can play a reinforcing role, improve the material hardness, mechanical strength, transparency, compactness and so on.
4.In the paper industry application as paper glue, paper whiteness and opacity, oil resistance, wear resistance, printing, feel smooth, good gloss, good quality and other advantages, while reducing the weight of the paper, anti-penetration of ink and so on.
5.Application in pesticide industry: It can be used in pesticides such as herbicides and insecticides, mainly to prevent agglomeration, control harmful organism production, and absorb soil pollutants.
6.In the application of toothpaste: as the main varieties of toothpaste friction, stable properties, non-toxic harmless, improve the transparency of toothpaste.
