Expanded vermiculite
Product Detailed
Expanded vermiculite. High grade vermiculite, top quality. Very competitive price. Very widely used in different industries.

      Vermiculite has excellent capability of heat insulation, freeze-proofing, gem-proofing, fire-proofing, and water-absorbing. Its volume could expand by 7-14 times, 30 times at maximum after heat treatment by holding at 800-1000°C for 0.5-1.0 minute. The loose expanded vermiculite will be made after the roasting, with the color turning to golden yellow or silvery white.

     The average bulk weight of vermiculite is 100-150kg/m3 with tiny air interlayer, after roasting in high temperature. Therefore it could preserve heat besides the capability we listed former.
