Expanded vermiculite

short description:

Expanded vermiculite is formed by expanding the original ore vermiculite at a high temperature of 900-1000 degrees, and the expansion rate is 4-15 times. Expanded vermiculite is a layered structure with crystal water between the layers. It has a low thermal conductivity and a bulk density of 80-200kg / m3 . The expanded vermiculite with good quality can be used up to 1100C . In addition, expanded vermiculite has good electrical insulation.

Expanded vermiculite is widely used in thermal insulation materials, fire protection materials, seedlings, planting flowers, planting trees, friction materials, sealing materials, electrical insulation materials, coatings, plates, paints, rubber, refractory materials, hard water softeners, smelting, construction, shipbuilding, Chemical industry.
