Aqueous Vermiculite Dispersion (AVD) fire extinguishing agent is a new, revolutionary technology that has key benefits over existing solutions utilising fixed and portable delivery techniques.
AVD is an aqueous dispersion of chemically exfoliated Vermiculite is applied in the form of a mist.
Vermiculite is the name given to a group of hydrated laminar aluminium-iron- magnesium silicates. Raw vermiculite consists of thin, flat flakes containing microscopic layers of water.
The chemical exfoliation of vermiculite produces microscopic, individual platelets that are freely suspended in water, which yields a stable aqueous dispersion of vermiculite.
