Intumescent Foam - Foam that expands when burned – Material Sample Shop

This sponge-like polyurethane foam expands to several times its size when exposed to open flames or high heat (above 300°C). 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 tox

CRC polyurethane foam designed to fill, seal, bond, retrofit, insulate and deaden sound in and around cracks and cavaties. The UL Classified, polyurethane foam forms a permanent, waterproof and airtight bond to masonry, wood, glass, metal and most plastics. It stops drafts, dust, moisture, insects and rodents. It cures to a semi rigid, closed cell foam that insulates to R 5 for each inch of foam. It uses a non flammable propellant and a 360 degree valve for safe and accurate dispensing.
