vermiculite flake after high temperature roasting, the volume can be rapidly expanded several times to dozens times, after the volume expansion of vermiculite is called expanded vermiculite,
It is layered structure, interlayer containing crystal water, bulk density in 50-200 kg/m3, small thermal conductivity, is a good insulating material. Good quality of expanded vermiculite, the highest temperature can reach 1100 ℃. In addition, expanded vermiculite has good electrical insulation. Expanded vermiculite is widely used in insulation, fire prevention materials, seedlings, flowers, trees, friction materials, sealing materials, electrical insulating materials, coatings, plate, paint, rubber, refractory materials, hard water softener, smelting, construction, shipbuilding, chemical industry, etc
