Chemguard has developed an alcohol-resistant aqueous film-forming foam (AR-AFFF) concentrate called ULTRAGUARD C135 for the municipal market.
The product, a high-performance 1-percent-3-percent AR-AFFF, was introduced at the Fire Department Instructors Conference in Indianapolis.
Characterized by a substantially lower viscosity than other 1-percent-3-percent polar solvent AR-AFFF concentrates, the company said ULTRAGUARD C135 can improve performance in all types of foam proportioning equipment on municipal fire apparatus, including in-line eductors, balanced-pressure systems and built-in foam systems.
ULTRAGUARD C135 offers superior firefighting properties, according to Chemguard, and is effective with blended gasoline additives, such as methyl tertiary butyl ether (MTBE) and ethanol-blended fuels. The product was described as ideally suited for municipal applications, where a variety of flammable liquid spills and fires may occur.
Formulated from special fluorochemical and hydrocarbon surfactants, high-molecular-weight polymers and solvents, ULTRAGUARD C135 is specified for use as a 1-percent proportioned solution on hydrocarbon fuels and a 3-percent proportioned solution on polar fuels, using fresh, salt or hard water. It can be transported and stored as a concentrate, offering both ease of use and substantial savings from reduced weight and volume, according to Chemguard.
Underwriters Laboratories successfully tested ULTRAGUARD C135 to the requirements contained in UL Standard 162, the Standard for Air-Foam Equipment and Liquid Concentrates.
Readily biodegradable, ULTRAGUARD C135 contains no perfluorooctane sulfonate (PFOS) or perfluorooctanoic acid (PFOA) ingredients, according to Chemguard.
