Description:

BILIN B2 PU Foam is a 3-in-1 solution for bonding, sealing, and insulation. Rated B2 for flame resistance, it self-extinguishes as soon as the fire is removed, minimizing fire risks. It fills gaps efficiently, blocks smoke leakage, and reduces noise and heat transfer in buildings. Curing upon contact with moisture, this CFC-free foam is a compact, easy-to-use choice for basic fireproofing and insulation needs.

Features & Benefits:

Self-extinguishing for passive fire protection
B2 fire rating (DIN 4102-1) for critical fire safety compliance
Better insulation performance than standard foams
Closed-cell structure: water-resistant, rigid, and dimensionally stable
Great installation adaptability for diverse scenarios
Easy to apply without specialized training
High expansion rate for cost-effective gap filling
Effective sound dampening and thermal insulation
Strong adhesion to common substrates
No shrinkage ensures long-lasting sealing effect

Application:

Fireproof window and door frame installation
Fire and smoke sealing between structural components (walls, floors, ceilings)
Sealing roof openings and construction gaps
Fire-rated applications like pipe penetration sealing and cold storage insulation
