Description

Polyurethane (PU) foam is an exceptionally versatile and high-performance material widely utilized in construction, insulation, and sealing applications. It is synthesized through an exothermic chemical reaction between polyols and isocyanates, generating a lightweight yet durable foam that rapidly expands upon application. This unique expansion property enables it to completely fill gaps, cracks, and irregular cavities, while simultaneously creating an airtight barrier that delivers superior thermal insulation, soundproofing, and moisture resistance.
