China Manufacturer wholesale thermal insulation vermiculite Manufacturer and Supplier

Thermal insulation vermiculite

short description:

Expanded vermiculite has the characteristics of porous, light weight and high melting point. It is most suitable for thermal insulation materials (below 1000 ℃) and fire insulation materials. After the experiment, the 15 cm thick cement vermiculite plate was burned at 1000 ℃ for 4-5 hours, and the back temperature was only about 40 ℃. The seven centimeter thick vermiculite plate is burned for five minutes at a high temperature of 3000 ℃ through fire welding flame net. The front side melts, and the back side is still not hot with hands. So it exceeds all insulation materials. Such as asbestos, diatomite products, etc.
