VERMICULITE - TERMIKAL
Vermiculite is a hydrated magnesium aluminium silicate which resembles mica in appearance. The name vermiculite is derived from the Latin “Vermicular”, meaning “to breed worm”.
Vermiculite, when subject to heat, has an unusual property of exfoliating or expanding into elongate concertina like particles. When expanded, it is lightweight, incombustible, compressible, highly absorbent, non-reactive. It can have high cation exchange capacity and the surface chemistry may be modified.
The unique properties of the exfoliated vermiculite are
-
Super Light weight
-
Inorganic
-
Fire resistant and not inflammable
-
Compressible
-
Highly absorbent ability
-
non- reactive
-
high Thermal and acoustic Insulation ability
-
High cation exchange
-
High surface area
-
Fire resisting up to 1100C
-
Free flowing and soft
Vermiculite is 100% natural material and environment friendly.
Exfoliated Vermiculite in industrial sector can be use us :
Floating insulation material in steelworks and foundries
Fire protection material can be use as loose fill in tanks and safe boxes
Component for low density refractory products
Safe Absorbent for chemicals, oil fuel and other Hazardous liquids
Safe packing materials as loose-fill for Hazardous and Breakable goods
Friction lining as an additive in manufacture of Brake pads
Carrier for nutrients and veterinary supplement in animals feed products
Carrier to transfer hazardous and toxic waste.
Expanded vermiculite in constriction sector can be us as :
Component for Passive fire protection products in spray and hand apply
Component to produce light and fire resistant boards
Component to produce decoration plaster and wall paper
Light concert on floor and roofs apply as Thermal and acoustic insulation
Light and soft concert to be apply as floor for Vinyl liner swimming pools
Thermal and acoustic insulation plaster for building and galleries
Fire resistant coating on steel construction
