Geprüfter Lieferant Sepiolite is rich of magnesium fibrous silicate clay mineral, the mainly chemical composition is (Si) and the magnesium (Mg) composes for the silicon, often assumes compact massive, earthy or fibrous, generally assumes the white, the gray or slightly brings the light red, dark green and brown. The adsorption performance and the heat-stable performance are excellent, thermostable and the electric insulation performance is good, the shrinkage is low, it's not easy to crack, as well as anti-salinity higher special performance.
Physical property:
The ore assumes clayey, the pellet is very thin, the naked eye is very difficult to distinguish, the color many to be pessimistic, or be brown. The sepiolite content is 20 generally--40%, other impurities are the quartz, the talc, the calcite and so on. This kind of ore reserve is rich, the application is widespread. The color is changeable, white majority, but also has light yellow, is light gray, is dark green, is not transparent, feel agglutination, the volume is big, proportion 2-2.5, non-toxic, tasteless , harmless , incombustible, the highest heat resistant 1750 degrees, the water-absorptivity in 1.5 times which is self-possessed, the catalysis, the absorptive quality is good.

1.The sepiolite has the shrinkage to be low, the plasticity is good, bears the alkali easily to dissolve, adsorption performance strong and so on unique industry performance, in addition, but also has the adsorption, the decolorization, the thermally stable, the corrosion resistance, the anti-radiation and the heat insulation, characteristics and so on insulation, mainly use in the building being sound-insulated, thermal insulation material, coating.
2. The product also uses in making the petroleum drilling mud;
3. Widely uses in keeping warm heat insulation raw material;
4. The drugs manufacture industry; The manufacture acid resistance drugs may use in a medicine grain of outlook, can cause the medicine to bear the oxidation to draw back changes.
5. Can be used as the filter aid for the wines and the oil class, enhances the transparency, and reduces the precipitation.
7. Uses in the rubber industry.
8. It can be used in cigarette's filtration and adsorb the noxious gas.
9.Widely used in specially the non-asbestos friction packing material in the recent years.
