Product Description

Fire proof PU Polyurethane Spray Construction Foam for Woodworking Packing Transportation 0

Description:

BILIN B2 PU Foam is a flame-retardant polyurethane foam certified to DIN 4102 B2 standards. It self-extinguishes immediately after the fire is removed, providing reliable fireproof sealing, bonding, and insulation for construction projects. Ideal for filling gaps, sealing cracks, and creating sound/thermal barriers, this foam expands upon contact with moisture and is free of CFCs, aligning with green building requirements.

Features & Benefits:

Self-extinguishing to prevent fire propagation
B2 fire class (DIN 4102-1) for fire safety compliance
Improved insulation coefficient for energy efficiency
Closed-cell structure: water-repellent, rigid, and dimensionally stable
Excellent installation and mounting performance
Easy application process
High expansion ratio for cost-effective gap filling
Effective sound reduction and thermal insulation
Strong adhesion to common building materials
No post-curing shrinkage for stable performance

Application:

Installation and sealing of fireproof doors and windows
Fire and smoke retardant sealing for wall, floor, and ceiling joints
Sealing of all openings in roof construction systems
Fire-rated filling and bonding tasks including pipe penetrations and cold storage insulation
