Product Description

750ml General Purpose PU Foam Acoustic Insulation No Shrinkage Weather Proof 0

Description:

BILIN B2 PU FOAM—easy to apply with a foam gun or straw. Expands and cures upon air exposure, forming durable, fire-safe seals compliant with DIN 4102 B2 standards. This flame-retardant material ceases burning instantly when fire is removed, ensuring superior safety. Perfect for insulation, gap filling, soundproofing, and sealing joints to block smoke and gas penetration. Offers strong bonding, fixing, and thermal/acoustic insulation properties. The CFC-free, environmentally friendly formula is versatile for construction applications, including crack sealing and structural reinforcement. Provides reliable performance for both residential and industrial projects.

Features & Benefits:

Self-extinguishing – Complies with fire safety standards.
B2 Fire Rating (DIN 4102-1) – Flame-retardant and smoke-resistant.
Closed-cell structure – Water-resistant, rigid, and long-lasting.
High expansion rate – Fills gaps efficiently for airtight sealing.
Excellent adhesion – Bonds strongly to various surfaces.
Thermal & acoustic insulation – Reduces heat transfer and noise.
No shrinkage – Maintains stability over time.
Easy application – Works with standard foam guns or disposable straws.
