This product is a mixture of C6 fluorocarbon surfactants developed based on the telomerization method, free of PFOS/PFOA.
It can be used as an additive in aqueous film-forming foam fire extinguishing agents, water-based fire extinguishing agents, etc., to reduce the surface tension of the solution, improve the oil-repellent performance and high-temperature resistance of the foam concentrate, and help the foam concentrate form a water film on the oil surface.
This product has good compatibility with anionic, non-ionic, amphoteric and other hydrocarbon surfactants.
