Fire Retardant B2 Pu Foam Polyurethane Insulation Material Expandable Spray Fire Rated Pu Foam

Description:

BILIN B2 PU FOAM is a flame-retardant, self-extinguishing polyurethane foam compliant with DIN 4102 B2 standards. It stops burning immediately when the fire source is removed, ensuring superior fire safety. Ideal for sealing, bonding, and insulation, it effectively blocks smoke and gas penetration in fireproof joints. Suitable for gaps, cracks, and sound/thermal insulation, this expanding foam cures with moisture, provides strong adhesion, and is CFC-free for eco-friendly construction use.
