VERMICULITE

GRANUTEC® / CRUDE AND EXPANDED

Vermiculite is a mica with a large amount of water weakly bound between the layers. Subject to a thermal shock, it has the capacity to expand by 10 to 15 times its volume. Vermiculite shows strong fire resistance, thermal and acoustic insulation, cation exchange and absorption properties.

GRANUTEC® is used in building (fireproofing, insulation, decoration), metallurgy, foundries, friction, horticulture (hydroponics), animal nutrition.

Expanded vermiculite is a light and absorbent culture medium for mixing with compost. It is particularly effective as a germination medium, for example boxes of catnip sold in supermarkets.
