What is vermiculite?
Vermiculite is a unique, ecofriendly, naturally occurring inert mineral with laminar structure from the hydromicas group.
It is a hydrated magnesium-aluminum silicate and may contain 20% water, but it expands greatly when heated at high temperatures (400-900˚С). The obtained product is called exfoliated vermiculite – a non-combustible, chemically inert, lightweight, highly absorbent and non-reactive material. When exfoliation occurs, vermiculite considerably expands its volume - from 5 to 10 times. When subjected to cooling, it retains its volume owing to the numerous minute air layers interleaved between the tiny mica ore-flakes.
According to the international Vermiculite Association (TVA), this mineral is one of the safest and most unique minerals in the world. Vermiculite is naturally occurring and can be extracted in various sizes and chemical forms. It is used in approximately 200 production areas. Owing to its high fireproof, heat-resistant and acoustic-insulation properties, porosity and mineral composition, vermiculite is widely used mainly in construction, industry, agriculture and horticulture.
Unique properties of vermiculite
- Fire-resistant
- High thermal insulation
- Hard to melt
- High acoustic insulation
- High water-holding capacity
- Eco-friendly
- Biological resistance and unlimited durability and usability
- Chemical inertness
- Low bulk density
- High porosity
- High ion-exchange capacity
- Radiation reflector
- Odorless
- Rich mineral content
Another unique property of exfoliated vermiculite is its low bulk density ranging from 65 to 130 kg/cub.m. depending on the particular fraction. It allows for using vermiculite as a packing material for transportation and storage of dangerous goods, hazardous chemicals, explosive materials as well as for long-term storage of fruit and vegetables.
