Versatile Fluorine Free Foam Alternative to AFFF/AR Fire Fighting Foams
Silvara APC+ is a versatile fluorine free foam for extinguishing hydrocarbon fuel, polar solvent fuel and solids fires. This effective concentrate forms a resistant foam with a high drainage time, insulates the fuel of the oxygen and extinguishes the fire. It is an alternative to the use of AFFF/AR products and is suitable for use at 3% with fresh, sea or brackish water.
Silvara APC+ can be used for Class A fires (solids) and Class B fires (hydrocarbon fuels and polar solvent fuels) using low expansion devices at concentration of use of 3% with fresh, sea or brackish water and medium expansion at 6%. It can be used with aspirating discharge devices (nozzles, foam chambers,…) with results in higher expansion ratios and longer drainage time.
Silvara APC+ can be easily proportioned using most conventional proportioning equipment such as: balanced pressure pump and bladder tank proportioners, around the pump type and venturis proportioners, and handline nozzles with fixed induction/pickup tubes.
Silvara APC+ has a biodegradability at 7 days up to 98% and 28 days at 100%, and so it is a “Fully biodegradable” foam concentrate
