Fumed silica and its properties?

Fumed silica (fumed silica) is one of the most important high-tech ultrafine inorganic new materials and is porous , non-toxic, odorless and pollution-free, high temperature resistant. At the same time, its chemical inertness and special thixotropic properties can significantly improve the tensile strength, tear resistance and wear resistance of rubber products. After the rubber is improved, the strength is increased dozens of times.

Rheology and thixotropy control of liquid systems, adhesives, polymers, etc., used as anti-settling, thickening, and anti-sag additives, HCR Reinforced with RTV-2K silicone rubber, it can be used to regulate free flow and act as an anti-caking agent to improve powder properties, etc. Vapor phase titanium dioxide, vapor phase alumina, mainly involved in the application fields: adhesives, coatings, paints, inks, batteries, toners, medicine, food, plastics, papermaking, cosmetics, silicone rubber, defoaming agents, composite materials, feed, etc. each field. Vapor phase silica is a white, non-toxic, odorless, amorphous inorganic fine chemical product. The atomic particle size ranges from 7 to 40 nanometers, and the specific surface area ranges from 70 to 70 m/g. It has various functions such as good reinforcement, thickening, thixotropy, extinction, UV resistance, and sterilization.

The particle size is very small, so the specific surface area is large, the surface adsorption force is strong, the surface energy is large, the chemical purity is high, the dispersion performance is good, the thermal resistance, the electrical resistance, etc. It has unique properties and plays an irreplaceable role in many disciplines and fields with its superior stability, reinforcement, thickening and thixotropy.

Nano silica is commonly known as “ultrafine silica” and is widely used in various industries as additives, catalyst carriers, petrochemicals, decolorants, matting agents, and rubber Reinforcing agents, plastic fillers, ink thickeners, metal soft polishing agents, insulation fillers, advanced daily cosmetic fillers and spray materials, medicine, environmental protection and other fields. It also provides new material foundation and technical guarantee for the development of related industrial fields.
