Unexpanded Vermiculite
Vermiculite is a mineral consisting of aluminium-ferrous-magnesium-silicate.
Which is in exfoliated form. which is natural,harmless.
raw vermiculite will be expanded to many times when heated at 850-1100 °C,
poisonless, odorless , corrosion-resistant, Non-combustible , natural refractory properties , Good thermal insulation ,low density ,etc
Vermiculite can be used to produce bitumen coated vermiculite screeds, construction coatings, lightweight concrete, etc.
