Foam Concentrates

Perimeter Solutions has been a pioneer in foam concentrates for nearly 40 years, introducing our first Class A foam, PHOS‑CHEK^® WD861, in 1986. Used on Class A fires started with ordinary combustible materials, such as cloth and paper, PHOS‑CHEK WD861 was created primarily for aerial firefighting. It was succeeded in 1988 by what has become the industry’s Class A workhorse, PHOS‑CHEK WD881.

In the early 2000s, we were among the first to introduce fluorine-free Class B foam concentrates to help firefighters extinguish fires caused by flammable and combustible liquids. We continued to expand our expertise and foam concentrate product offerings with the acquisitions of SOLBERG and AUXQUIMIA, and today we are considered an industry leader in fluorine-free technology.

Our foam concentrates are also used in our comprehensive line of fire extinguisher additives (for Class A, B, and F fires), and for foam solutions specifically designed to be used for Training and Exhibition purposes.

Our Class A, Class B, Fire Extinguisher Additives, and Training Foam pages have more details on our foam concentrate technology.
