B2 Fire Retardant Self-extinguish Pu Foam Chemical Spray Fire Rated Polyurethane Pu Foam

Description:

BILIN B2 PU FOAM is a flame-retardant, one-component polyurethane foam that meets DIN 4102 B2 standards—ensuring non-flammability and immediate self-extinguishing when fire is removed. Perfect for fireproof sealing, it effectively blocks smoke and gas penetration in joints and gaps. With excellent bonding, fixing, and insulation properties, it’s ideal for construction, soundproofing, and thermal insulation. Easy to apply via foam gun or straw, it expands upon contact with air moisture, providing durable, high-performance seals.
