Company Information
We are Tianjin ZhongFa Sepiolite Co. based in Tianjin , China. We are member of Tradekey.com since December, 2008. Our business is related to Minerals & Metallurgy industry and we specifically deal in sepiolite. Please find our product details below:
sepiolite
Description: Sepiolite is silicate clay mineral in fibre form which is rich in magnesium, and it is also called magnesium and silicate mineral in moisture chain layers. It can be divided into soil Sepiolite (Stereoplasm sepiolite) came from deposition, and massiveness Sepiolite (light Sepiolite) came from hydrothermal deposit.
The specific gravity of the lightness is 2-2.3, hardness is 2-2.5. Nontoxic and odorless, it is harmless to people. its melting point is 1500-1700, so it’s heat resistant. It is low in contraction, but high in plasticity. It dissolves in hedrochloric acid. It is insulating and salt resistant, etc.

Main Uses :
It can be used to purify oils, to make medical casing, to make organic coolant in refining atomic reactor, to absorb radioactive waste. The processed sepiolite mixed with some active carbon in an ideal material in making filter tip of cigarettes.
　Mixed with cement, it helps to reduce contraction and leave no gaps and leak no water. Added to painter, the painter can from a sediment to improve its quality.
　It can be used as the fine mud material in well drilling for terrestrial heat, for petroleum and halite. It is particularly applicable for deep well drilling.
　It can be used to make soap and detergent in the place of fatty acid, to improve quality and clearance.
　Used as additives of cosmetics , it can absorb bacteria. Mixed with glass fibre, sepiolite can be made into inorganic noncombustible paper.
　It can be used to improve the soil as suspended agent in fertilizers and carrier of chemicals. It can also be used as additive of fodder, coherent agent, improving agent for animals, oil-clearing agent in fodder sites, etc.
　It can be used to produce original device of special pottery, atomic radiation-resistant apparatus in making atomic energy, rockets and satellite.
vermiculite
Vermiculite
Description: Essentially vermiculite is one member of the micaceous hydrated silicate minerals, resembling mica in appearance. When heated to a temperature of about 850-950℃, as water flashing into steam, raw vermiculite instantly expands (exfoliates) up to 15-20 times, maximum 30 times its original bulk volume, and during expansion its color change from gold brown into silver white. It has the action of fireproof, heat insulating, sound and moisture absorbing, non-toxic, lightweight and disease free and so on.
Properties:
With the characteristic of light Weight, thermal stability and inertness, disease free and non toxic, non abrasive, highly (water, nutrients, air and so on) absorption, insulates and minimizes soil temperature fluctuation, won’t deteriorate in storage, vermiculite becomes the new and ideal material in construction, industry and agriculture.

Mica Mica powder
Description: Mica is a group of aluminum silicate minerals with layer-structure, and rich in elements of potassium(K), aluminum(Al), magnesium and lithium etc. Dolomite (White Mica) is one of the similar sub-categories in mica group. It is transparent with no color or light color, and possesses the glass’s shine. Its Mohs hardness is about 2-2.5, specific density is 2.7-3.5. Dolomite possesses lots of excellent properties, for example electric insulating, high temperature proof, acid and alkali resist, and corrosion proof ect.

Applications:
Mica powder can be used as prior filler in paint and coating.
Mica powder can be applied in protecting layer of welding rods, conducting wires and electric cables.
Mica powder is also the basic raw material for mica porcelain products.
It can be used as suspended substance in fire-fighting dry powder.
It can be taken as filler, shelter, lubricating substance, a drawing of patterns in plastics, rubber, asbestos products and sealing materials.
It can also be used as filler in degreasing agent of cosmetics, in insulating materials of high-frequent electric waves and acid-durable products.
It can be used as coating in models of forecasting metal, the brightening material in aluminum and paint in electroplating.
