Model : W-300
Description : W-300 is hydrophilic fumed silica. It is high purity and fluffy powder with typical specific surface 300 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-300 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-300 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, e.g. pharmaceuticals, cosmetics
▪ Gelification of battery acids
▪ Rheology control of greases and lubricants
