Product Description

Fire Retardant B2 Pu Foam Polyurethane Insulation Material Expandable Spray Fire Rated Pu Foam 0

Description:

BILIN B2 PU Foam is a flame-retardant, self-extinguishing polyurethane foam certified to DIN 4102 B2 standards. It ceases combustion immediately when the fire source is removed, ensuring top-tier fire safety protection. Designed for multi-functional use in sealing, bonding, and insulation, it acts as a reliable barrier against smoke and gas penetration in fireproof joints. This moisture-curing expanding foam forms strong adhesive bonds and is free of CFCs, making it a sustainable choice for eco-conscious construction projects.

Features & Benefits:

Self-extinguishing to prevent fire spread
B2 fire classification (DIN 4102-1) meets strict fire safety requirements
