super white sepiolite powder used for plastic industry
manufacturer directly supply sepiolite powder and raw sepiolite
sepiolite/sepiolite mineral/sepiolite powder
We are a Chinese manufacturer who produce sepiolite for more than 20 years. We can directly supply you best quality and lowest price. Sincerely invite you to visit our factory.
Sepiolite is a silicate clay mineral in fibre which is rich in mangnesium, and it is also called mangnesiumand silicate mineral in moisture chain layers.lt can be divided into soil sepiolite(stereoplasm sepiolite) comingfrom deposition and massiveness seoiolite (light sepiolite) coming from hydrothermai deposit. The specific gravity of the lightness is 2-2.3,hardness is 2-2.5.poisonless and odourless, it is harmless topeople. lts melting point is 1500-1700, so it’s heat resistant. It is low in contraction,but high in placticity. lt dis-solves in hedrochloric acid. lt is insulant and salt resistant,etc. Sepiolite♦ 1.1) Adsorptivity: porous, wide area, strong adsorptivity. | |
2) Catalyst: It has a strong affinity on the organic matter, It can take direct action with organic reactant, and generate organic mineral derivatives. It has high chemical adhesion. | |
3) Light weight: | Specific Gravity:2-2.3, weight :1.2-1.5 tons / M3, hardness: 2-2.5, |
non-toxic, odorless, harmless to human body, low shrinkage rate, good plasticity and insulation, high resistance to salinity. | |
It can resist high temperature, its melting point is 1500 -1700 . | |
It can be dissolved in hydrochloric acid.. | |
