AVD stands for Aqueous Vermiculite Dispersion
The technical side:
- AVD is a stable suspension of vermiculite platelets with a D90 of 180 microns (0.18mm).
- AVD is non-flammable and has excellent insulation properties.
- It is approximately 17% Vermiculite and 83% water.
- It has a viscosity of 3000 cPs - generally the same as double cream.
What is Vermiculite?
Vermiculite is a naturally occurring mineral: aluminium – iron – magnesium – silicate that is mined all over the world.
It is non-flammable and has excellent thermal insulation properties.
It is chemically and physically inert
Vermiculite mineral is exempt from REACH regulations
How does AVD work?
Our Firechief Lithium-ion Battery Safety Range includes Lithium-ion Battery Fire Extinguishers, fire blankets, suppression kits and fire-resistant containers, these products are designed to put out and keep out Lithium-ion battery fires. For more guidance on what to use on certain applications, see our product selector.
What are the benefits of AVD?
AVD fire extinguishing medium has a number of key benefits over existing solutions:
• AVD is water-based, therefore, it extinguishes the fire and cools the cells
• AVD is film-forming and creates an oxygen barrier
• AVD encapsulates the fuel source to prevent re-ignition
• AVD electrically insulates -35kV Dielectric test
• AVD prevents the propagation of the fire
• AVD impacts on each element of the fire triangle
