Crude Vermiculite 32 Mesh 3-101

Vermiculite ore can rapidly expand by several or tens of times in volume after heated up under high temperature, with the average capacity being 100-130kg/m3 and also tiny air layer, which makes it an excellent building material for heat preservation, sound absorption and cold resistance as well as industrial filler, coatings and refractory material. Besides, the expanded vermiculite is also a good heat insulation material as it is small in thermal conductivity and its capacity is between 50-200kg/m3. Good-quality expanded vermiculite can still be workable up to up to 1100ºC. In addition, expanded vermiculite is good in electric insulation, light in capacity and is cold-resistant, heat-preserving, heat-insulating, sound-absorbing, etc. Therefore, it can be widely used in construction, electric power, petroleum, metallurgy, textile, agriculture, food industries and etc. Applied into the construction industry, it can be used in thermal insulation, sound absorption and coating materials; applied in agriculture, as soil improver and auxiliary of fertilizers, expanded vermiculite is light in terms of weight, absorptive of water and fertilizer, and can be used for 3-5 years without putrefaction. What's more, it is carrier of animal feed, deodorant, animal drugs and so on. It can also be used as pesticides, fungicides, disinfectant, organic compounds (camphor) and can provide a good media for storing vegetables as well as roots, stems and leaves of other rare plants. Vermiculite has adsorption property for radioactive elements and also can handle some waste water of radioactive elements.
