Fumed Silica 200

Product name: Fumed Silica 200 Chemical name: Silicon dioxide Molecular Formula: SiO2 Appearance: White solid colloidal particle Specification: Item Specification Specific surface area, m2/g 200+/-25 pH value 3.6-4.3 Loss on drying, %(m/m)≤ 2.0 Loss on ignition, %(m/m)≤ 2.0 Apparent density, g/l 30-60 Viscosity, mP.s 500-100 Properties: Fumed silica is one of the nanopowders that appeared earliest and achieved industrialization earliest. It is a white, loose, amorphous, non-toxic and pollution-free inorganic non-metallic oxide. The primary particle size is between 7~40rim. The specific surface area is generally larger than 100m2/g. Due to the nano effect, it has excellent reinforcement, thickening, thixotropic, insulation, matting, anti-sag properties. Product uses: It is widely used in rubber, plastic, coating, adhesive, sealant and other polymer industry fields. Packaging specifications: Plastic woven bag with inner plastic film; net weight is 10kg or according to customer requirements
