Explosion Suppressant Foam is a reticulated polyurethane foam and is used in fuel tanks where the possibility of fuel tank explosion exists. Also known as ESF, or Safety Foam, the product was invented in the late 1960s when the United States Air Force began using reticulated polyester polyurethane foam to suppress fires and explosions inside fuel tanks.
Explosion Suppressant Foam has now been used for over 30 years and has found thousands of successful applications in aircraft, boats, military vehicles, competition and emergency vehicles.
We stock the two common types:
Yellow or Type 2 which is commonly used for petrol & E85 Ethanol fuel (E85 should be drained from the tank when the vehicle in not in use)
Blue or Type 4 which is commonly used for diesel, methanol & water.
The foam is stocked in various sized pieces but sold in 1 litre quantities (a litre equates to a cube of 10 x 10 x 10cm).
