Description : is hydrophilic fumed silica. It is high purity and fluffy powder with typical specific surface 200 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, 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. 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
