Moisture Proof Fire Retardant Expanding Foam Portable And Convenient

Description:

DIN 4102 B2-certified, this PU foam is highly flame-retardant and self-extinguishing, stopping combustion immediately when the fire source is removed. Ideal for fireproof joint sealing, it effectively blocks smoke and gas penetration while providing strong adhesion, thermal insulation, and soundproofing. Suitable for gap filling, crack sealing, and structural bonding, it cures with moisture, ensuring durable and reliable performance. The eco-friendly formula contains no CFCs and offers excellent mounting stability for a wide range of construction applications, from installation fixes to acoustic and thermal insulation.

Features & Benefits:

B2 Fire Rating (DIN 4102-1) – Enhanced flame resistance for critical applications.
Self-Extinguishing – Stops burning once the flame source is removed.
Closed-Cell Structure – Water-resistant, rigid, and dimensionally stable.
High Expansion Rate – Fills gaps and voids completely for airtight sealing.
Thermal & Acoustic Insulation – Reduces heat transfer and dampens sound.
Strong Adhesion – Bonds securely to most construction materials.
Non-Shrinking – Maintains stability over time without cracking or settling.
Easy Application – Cures with ambient moisture for quick installation.

Application:

Fire-rated door and window installations.
Sealing joints in walls, floors, and ceilings to block fire and smoke.
Penetration sealing for pipes, ducts, and electrical conduits.
Roof and facade gap filling for weather and fire resistance.
Insulation in cold storage or industrial environments requiring fireproofing.
