What is Vermiculite
Vermiculite is the geological name given to a group of hydrated laminar minerals which are aluminum-iron magnesium silicates which have the appearance of mica, and are found in various parts of the world. When processed for use, the mineral is subjected to intense heat, expanding it into accordion-shaped granules with countless layers of thin plates
Once
thermally expanded, this industrial mineral has a multitude of uses as a specialty
raw material. It has a unique combination of properties including low bulk
density, heat and fire resistance, and a large surface area for superior absorbency
and chemical inertness. Used as an aggregate for refractory brick and castables,
U/L rated doors, safes, cabinets, ladle insulation and metallurgical processing;
as a general purpose filler for industrial composites, friction materials,
and lightweight concrete; as a carrier and bulking agent for lightweight fertilizers
and animal feeds; and as an absorbent for chemical packaging, spill clean-up
and cushioning fragile items.
