The expansive fireproof foam adhesive is a two-component, low-density elastic foam sealing material. It is halogen-free and asbestos-free, with excellent smoke tightness, air tightness, and water tightness, providing effective thermal and fire insulation. The system features a 30-year long-term fireproof performance, withstands 200kPa explosion pressure, and offers up to 3 hours of fire resistance—comparable to 3M FIP-1 Step fireproof foam and Hilti CP620 with a higher cost-performance ratio.

● No sagging, fast curing—suitable for hard-to-reach sealing scenarios.
● Expands 5–7 times during installation and further swells when exposed to fire, maintaining fire resistance >3 hours.
● Remains flexible after installation, enabling easy secondary construction.
● Exhibits excellent adhesion without requiring base materials.

Suitable for various penetration applications, hard-to-access openings, and post-installation sealing for secondary penetrations. Can be painted over with other coatings after application.
