Fire-resistant polyurethane foam
One-component low-expansion modified polyurethane foam with low flame spread characteristics intended for areas that require greater resistance to combustion. It is used for filling, insulating, and installing electrical installations, duct penetrations, fire doors, vaults. Hardens with air humidity and adheres well to all construction materials. After application, it expands up to 50% in volume, so only partially fill the openings. Hardened foam ensures a strong bond and features good insulation properties.
