Specification of titanium dioxide nanopowder: The particle size is very small: an average particle size of 5 nm. Good dispersion performance: 5 nm titanium dioxide has good dispersibility and can be self-dispersed into pure water without stirring. The dispersed liquid can be sprayed onto the surface of the furniture and the wall to form a uniform nano-coating to purify the indoor air. High catalyt...

Nano silica powder is a filler for reinforcing high-temperature vulcanized silicone rubber. The silica nanopowder aggregates have a good reinforcing effect on the silicone rubber. After adding SAT NANO nano silica powder to the rubber, a microcrystalline region with silica as a nucleus is formed, which increases the physical cross-linking point. Crystallization is more likely to occur and the stre...
