SUOLONG ECO SFFF 3%
Fluorine-free (PFAS-free) synthetic foam concentrate for ARFF, ICAO Level B
SUOLONG ECO SFFF 3% is a synthetic fluorine-free foam (SFFF / F3) concentrate proportioned at 3%, built on a patented blend of fluorine-free surfactants. It is purpose-designed for Aviation Rescue Fire Fighting (ARFF) vehicles, forming a vapour-suppressing blanket on Jet A and Jet A-1 spills to control Class B aviation-fuel fires with strong burnback resistance. Why fluorine-free matters: PFAS ("forever chemicals") used in conventional AFFF are being restricted worldwide. The EU is advancing a broad PFAS restriction under REACH, and a number of countries and US states already ban or phase out fluorinated firefighting foam at airports. SUOLONG ECO SFFF 3% contains no fluorinated surfactants, polymers or other organohalogens — it is genuinely PFAS-free, readily biodegradable, and a practical path to compliance for operators replacing legacy AFFF stocks. Performance and compatibility: effective on Class B hydrocarbon fuels (kerosene, Jet A / A-1); suitable with fresh and sea water and with aspirating discharge devices such as foam branch pipes and monitors. It is not suitable for polar / water-miscible fuels such as alcohols, ketones, esters and ethers. The low 3% proportioning rate reduces logistics and storage burden. Storage and packaging: shelf life of over 10 years stored at −10 °C to +55 °C in original containers, approved bladder tanks, stainless steel, high-density polyethylene or fibreglass. Available in 20/25 L cans, 200 L drums and 1000 L IBCs. Approval: type-approved to ICAO Level B.
