White carbon black /advosil-20 precipiteted silica can be dissolved in caustic alkali and hydrofluoric acid, insoluble in water, solvents and acids (except hydrofluoric acid). High temperature, flammable, tasteless, odorless, has excellent electrical insulation.
Advosil-20 silica is used widely in silicon rubber, construction sealant, coating, electron and electric, aerospace, medicine and medical material, resin processing, printing ink, pesticide and other industries.
Advosil-20 is a power and granual pracipitated silica.
