fumed silica silicon dioxide

Product Description

Model : W***0 Description : W***0 is hydrophilic fumed silica. It is high purity and fluffy powder with typical specific surface **0 g/㎡. Furthermore, it is characterized by an X-ray amorphous structure. Along with the traditional ▪ Polyester ▪ RTV silicone sealant and HTV silicone rubber ▪Adhesives ▪ Printing ink ▪paints and coatings applications, W***0 is used with increasing success in high technology fields. The particle nature and high purity of fumed silica play key roles in the electronics and optical fibers industries. W***0 is of an especial highly pure quality and has been developed for these applications. Positive effects: ▪ Optimum adjustment of rheology during processing ▪ Reinforcement of silicone elastomers ▪ Thickening of non-polar liquids ▪ Free-flow of foodstuffs and industrial powders ▪ High chemical purity ▪ Excellent insulation properties, even at high temperatures ▪ Conversion of liquids to powders, ***** pharmaceuticals, cosmetics ▪ Gelification of battery acids ▪ Rheology control of greases and lubricants Typical Parameters: DESCRIPTION UNIT TYPICAL VALUE Bet specific surface area g/㎡ **0 ± *0 PH of suspension 4.**4.3 Loss on heating (2hr.at **5 ℃) wt％ ≤ 0.6 Loss on calcinations (2hr.at **6 ℃) wt％ ≤ 0.6 Silicon dioxide SiO2 content wt％ ≥ *9.8 Bulk density g/l *0 Package details: *0kgs/bag, *8bags/pallets, 3.6 tons in each *0FCLcontainer
