Aerosil is a very clean non-porous amorphous silicon dioxide with a particle size of from 5 to 40 nm. Particles of Aerosil physical form flocculent aggregates, so the amount of Aerosil in fact, 98% filled with air: if true density of SiO2 is 2.2 g/cm3, the apparent density of Aerosil - 40 - 60 g/L.
The particle size of the aerosol is 10 to 40 nm for 150 marks, 175,200; 5-20 nm for grade 300; 5-15 nm for the brand 380.
Aerosil has very low thermal conductivity and is a valuable insulating material. He has good adsorption properties, especially to polar substances.
As filler Aerosil found a variety of applications, which is completely based on such properties as extremely small particles and their homogeneous, spherical shape and a high degree of purity. From a chemical point of view, all properties of Aerosil are determined by the presence on its surface silanol ≡ Si - OH) and siloxane ≡ Si - O - Si ≡ groups.
Adding Aerosil in the liquid system, there is the effect of thickening, which is particularly important in the manufacture of products such as lubricants, paints, varnishes, glues, etc.
Aerosil is the most active silica filler. He currently finds application in various fields. So, Aerosil is used as high-quality filler in the production of rubbers, as thickener lubricants, adhesives, sealants, polyester and epoxy resins, paints, varnishes, to impart flowability of the powder and granular products (for example, mineral fertilizers, washing powders, etc), as well as in the textile, pharmaceutical, perfumery and food industries.
