Installation and Maintenance HD AFFF is Aqueous Film Forming Foam concentrate (AFFF) has characteristic of film forming, due to which flame is rapidly knocked down and sealing of fuel surface is effectively achieved. HD AFFF is formulated with Fluorinated surfactants, hydrocarbon surfactants and stabilisers to give best performance and long shelf life. Due to presence of Fluorocarbon surfactant the foam has a positive spreading coefficient on the surface of the fuel, giving fast coverage and thereby helping the fire fighters in saving precious time. HD AFFF can be used with fresh or sea water. HD AFFF is available as 3% and 6% Foam Concentrates.
Foam (AR-AFFF)
HD AR-AFFF is a foam concentrates Installation and Maintenance containing polysaccharide, which forms a pseudo plastic bottles on the surface of polar solvents. It forms a cohesive thin polymeric film at the interface between foam and the water soluble Polar solvents. This thin polysaccharide film fire safety the foam without destruction of aqueous film by polar solvents. The polymeric film has self-sealing characteristics whereby the film, if disturbed gets regenerated by itself. HD AR-AFFF forms an aqueous film like AFFF on the surface of hydrocarbon solvents. AR-AFFF is also known as ARC (Alcohol Resistant Concentrate), ATC (Alcohol Type Concentrate), AGFFF (Aqueous Gel Film Forming Foam), MPF (Multipurpose Foam) and UF (Universal Foam). It exhibits quick fire control and is ideal for prompt intervention. HD AR-AFFF is available in type 3 x 6% concentrate and 3 x 3% concentrate. It is also available in freeze protected range.
HD FP is mainly based on protein material, which gives good sealing and excellent burn back resistance. However the spreading of the foam is slow. This limitation is overcome by incorporating fluorinated surfactant in the formulation; without affecting heat stability. HD FP is formulated with hydrolysed protein, fluorochemicals, metal salts, special stabilizers and preservatives to give the best performance and satisfactory storage. It is highly reliable, cost effective and efficient on massive hydro-carbon fires. It gives resistance to fuel pick-up and is suitable for sub-surface applications. HD FP is suitable for long pre-burn fires on petroleum tank farm fires, oil jetties, refineries and offshore oil platforms. HD FP is available as 3% and 6% Foam Concentrates.
Foam (FFFP)
HD FFFP is based on protein material, which gives good sealing and excellent burn back resistance. The limitation of protein foam regarding slow spreading is overcome by incorporating fluorinated surfactant in the formulation; spreading is improved without affecting foam stability. HD FFFP is formulated with hydrolysed protein, fluoro chemicals, metal salts, special stabilizers and preservatives to give the best performance and satisfactory storage. It is highly reliable, cost effective and efficient fire extinguishing agent which gives rapid extinguishment, high resistance to heat and fuel pick- up. HD is suitable for fighting fires of non-polar, flammable solvents. HD FFFP is available as 3% Foam Concentrates.
