Description


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


Description:

BILIN B2 PU Foam is a one-component, flame-retardant polyurethane foam that meets DIN 4102 B2 standards, offering non-flammability and instant self-extinguishing properties after fire removal. It is specially formulated for fireproof sealing, effectively blocking smoke and gas from passing through joints and gaps. With outstanding bonding, fixing, and insulation performance, it is the go-to choice for construction, soundproofing, and thermal insulation projects. Applicable via foam gun or straw, it expands when exposed to atmospheric moisture, creating durable, high-performance seals for long-term use.

Features & Benefits:

Self-extinguishing to contain fire spread
B2 fire class (DIN 4102-1) for reliable fire protection
Enhanced insulation factor for reduced energy loss
Closed-cell structure: water absorption resistant, rigid, and stable
Excellent installation and mounting efficiency
Simple application with gun or straw
High expansion rate for maximum gap coverage
Efficient sound and thermal insulation
Superior adhesion strength
No shrinkage for stable, long-lasting seals

Application:

Fireproof door and window installation and sealing
Fire and smoke retardant sealing for wall, floor, and ceiling joints
Sealing all openings in roof construction
Fire-rated filling and bonding work including pipe penetrations and cold storage insulation
