Description:
BILIN B2 PU FOAM is a self-extinguishing (DIN 4102 B2), non-flammable polyurethane foam that stops burning immediately when the fire source is removed, ensuring safe and reliable performance. Designed for fireproof sealing, bonding, fixing, and installation, it excels in sound and thermal insulation. The foam expands and cures with moisture, providing secure adhesion and excellent gap-filling for joints, cracks, and voids. Ideal for construction applications, it offers gas separation and durable sealing while maintaining high mounting strength. Environmentally friendly and CFC-free, it works with foam guns or straws for precise, efficient application in diverse building projects.
