Imtumescent flame retardant technology is a widely used fire protection technology during the past 30 years in the world.

Its application principle is that the volume of thermal expansion flame retardant will rapidly expand when the temperature reaches above 180℃, and the expansion body will eventually form a porous and hard insulation layer to prevent further heat diffusion to the base material.

Base on the imtumescent flame retardant technology, we had developed a series of lighter, faster and easy installation “HK” series cable and pipe penetrations. And we provide a totally fire protection solutions for marine and offshore engineering when the cables, plastic pipes, metal pipes, and multi-core pipes pass through the “B” class, “A” class or “H” class decks and bulkheads.
