Suolong SF-2% HEF High Expansion Fire Fighting Foam

PFOA PFOS Fluorine Free - Suolong SF-2% HEF Fire Fighting Foam Concentrate What's Included? ✔️ High Expansion Synthetic Technology ✔️ Rapid Fire Knockdown ✔️ Dual Marine Certification High-Performance High Expansion Firefighting Foam for Hydrocarbon Fires For high-risk environments requiring immense fire-blanketing power, Suolong SF-2% HEF Fire Fighting Foam is the ultimate choice. This premium synthetic foam concentrate is specifically engineered to cover massive surface areas, making it highly effective at smothering large-scale spills of non-water-soluble flammable liquids. Formulated to combat volatile Class B hazards, Suolong 2% HEF specializes in hydrocarbon fires, providing a rapid-acting defense against oil spills, crude fires, and aviation fuel accidents. Fully compliant with the Marine Equipment Directive (MED) and CCS frameworks, this concentrate is built to deliver reliable, professional-grade suppression in hazardous marine and heavy industrial sectors. Advanced Volumetric Blanket & Suppression Technology Suolong SF-2% HEF utilizes an advanced synthetic surfactant base to break the fire triangle through total surface isolation: Massive Expansion Ratio: Features an expansion profile ≥ 600, allowing medium and high expansion generators to convert minimal concentrate volumes into a massive, dense foam blanket that starves the fire of oxygen. Hydrocarbon Fire Specialization: Quickly suppresses aviation fuel and oil fires by creating a vapor-tight barrier over liquid fuel surfaces, preventing re-ignition with a burn-back resistance time of ≥ 10 minutes. Dry Chemical Powder Compatibility: Demonstrates excellent compatibility when used in twin-agent systems alongside all standard dry chemical powder suppressants. Key Features & Global Marine Approvals MED / Wheelmark Approved: Certified under international maritime frameworks (IMO MSC/Circ.670), making it mandatory fire protection for offshore platforms and marine vessels. Optimal Drainage Profile: Delivers high thermal stability with a 25% drainage time of ≥6.0 minutes and a 50% drainage time of ≥ 10.0 minutes to maintain structural integrity over hot fuel pools. Extreme Cold Tolerance: Highly stable across wide storage variations; freeze-resistant formulations remain perfectly fluid and operational down to -20°C. ✅ Ideal For: Aviation & Aerospace, Oil & Gas Infrastructure, Marine & Shipping, Hazardous Enclosures ✅ Compliance: IMO MSC/Circ.670, Marine Equipment Directive (MED), CCS Mixing & Operational Guidelines Precise 2% Induction: Designed for exact induction metering at a 2:98 ratio (2 parts concentrate to 98 parts water) using fresh or seawater through medium or high expansion foam equipment. Non-Alcohol Resistant: This foam concentrate is highly specialized for non-water-soluble hydrocarbons (oil, petrol, jet fuel). It has limited effectiveness on polar solvents or water-miscible flammable liquids like alcohols and ketones.
