It is mainly used in the production of silicone rubber (HTV, RTV), resin coatings, paints, inks, electronics, paper making, medicine, cosmetics, toothpaste, adhesives, plastics and other industries. Its characteristics are that it has good anti precipitation, anti vertical flow, thickening thixotropy, anti settlement, improving dielectric properties, promoting free flow, self-cleaning, etc. It is a free flow additive with excellent effect. The positive and negative systems are added with control agents, including the carrier of components (catalysts, etc.), Granulating aids, processing aids, anti caking agents, stabilizers
Due to its unusual particle characteristics, fumed silica is considered to be a good product in industry. Very small particle size and huge surface area of fumed silica. Its high purity and its chain forming tendency make it a class of its own.
Among the effects of fumed silica on product performance, the most important is to change the flow characteristics of the product by forming an alternate network structure and destroying the structure according to the size of the existing shear force, so that the flow can be controlled according to the strict requirements of the configurator.
Another unique function of fumed silica is to improve several different properties of the same product at the same time, which is difficult to achieve with other single substances or even several substances.
When fumed silica is used in coatings, adhesives, cosmetics, inks, plastics, and products such as adhesives, it can simultaneously improve or obtain thickening, thixotropy, solid suspension and transparency. Vapor silica can promote the free flow of dry powder, granular materials and pellets, which is extremely useful in food, cosmetics and various chemical industrial products.
Packaging: 10kg/original paper bag.
· detailed description:
· Vapor phase white carbon black is one of the new ultra-fine inorganic materials. Because of its small particle size, it has large specific surface area, strong surface adsorption, large surface energy, high chemical purity, good dispersion, thermal resistance, resistance and other aspects of special performance. With its superior stability, reinforcement, thickening and thixotropy, it has unique characteristics in many disciplines and fields, and has an irreplaceable role. It is widely used in various industries as additives, catalyst carriers, petrochemical industry, decolorizing agent, matting agent, rubber reinforcing agent, plastic filler, ink thickener, metal soft polish, insulation and thermal insulation filler, advanced daily cosmetics filler and spraying materials, medicine, environmental protection and other fields.
