Intumescent Foam - Foam that expands when burned stainless steel

Intumescent Foam - Foam that expands when burned stainless steelThis sponge like polyurethane foam expands to several times its size when exposed to open flames or high heat (above 300C). The heated foam forms a solid char, which resists further heat degradation. Used for: Expanding intumescent materials are used for seals that rapidly close off the passage of fire, smoke, and toxic gases during a fire. It is used for doors, ventilation ducts, and pipe and cable lead ins. It can be packed around plastic piping,
