1) high quality Silicon dioxide powder
ISO 9001 and ISO14000 Competitive price packing --as you required M W --60.084
2) uses Take off the wet will be used as dehydrant, desiccant, moistureproof agent and air humidity regulator. Also used to dry gas. Also used as catalyst and catalysts, silicone rubber cutting body of reinforcing agent, and textile industry of sizing agent with.
3) specification
NoticeAlthough commonly it can not damage the flatting grains in the dispersion processbecause of the "excess" grinding, it may reduce the flatting effect and increasethe viscosity if it is ball milled or tri-roller milled for a long time.
