Product Description

Vermiculite is a natural mineral that expandsunder high temperatures.Vermiculite cancreate excellent pore structure in the matrix,making it have good breathable pores

• Vermiculite is a layer-structured metamorphic rock of gibbsite silicate. Rich in magnesium.
• It comes from hot-liquid-eroded or weathered phlogopite. 
• When it is heated to lose water and expands, lt turns curvingas a leech. Therefore is called vermiculite.
• It can be divide into original vermiculite and expanded vermiculite. 
• It can also be divided into golden vermiculite and silver white vermiculite according to its color
•  
• Vermiculite is a mineraloid of hydrated laminar magnesium-aluminum-ironsilicate. Its chemical composition greatly varies and chemical formation could be simplified as ( Mg.Fe..Fe.. )3[(SiA)4O10][OH]24H2O. When heated to a temperature of about 850-950ºC, it instantly expands (exfoliates) up to 15-25 times as water flashing into steam, maximum 30 times its original bulk volume. There is a color change during expansion from golden brown into silver white depending upon the composition of the vermiculite and temperature. With such prominent characteristics as being fireproof, heat insulating, sound and moisture absorbing, non-toxic, lightweight and disease free, it is widely used in construction, chemical industry, petroleum, electronics, light industry, environmental protection and as medium of agricultural chemical products etc.
  Vermiculite is a member of the phyllosilicate group of minerals, resembling mica in appearance. It is found in various parts of the world, vermiculite is basically a hydrated phlogopite mica which has the remarkable ability to expand to many times its original volume when heated at 850 -1100°C. According to color, vermiculite flakes divides into golden vermiculite flakes and silver vermiculite flakes. The main application of vermiculite is to produce different sizes expanded vermiculite.
