FG3291 PUR Adhesives for Fire-Resistant Fabric Lamination

The Advantages of Our Fire-Resistant Fabric PUR Adhesive

1. Extreme Temperature Resistance & Heat Isolation

Unlike conventional adhesives that fail below 250°C, our advanced PUR adhesive layer resists carbonization at temperatures up to 400°C. It supports aerospace-grade bonding processes to achieve 500°C+ instantaneous heat isolation.

2. High Peel Strength & Anti-Delamination

Solves the critical flaw of reflective layer delamination in traditional heat-resistant materials. It delivers an exceptional peel strength exceeding 12 N/cm (ISO 11339), maintaining structural integrity even after repeated use.

3. Dynamic Durability & Flex Resistance

Creates a resilient, cross-linked thermoset bond capable of withstanding over 100,000 dynamic bending cycles, making it ideal for flexible firefighting and industrial protective garments.

4. Broad Substrate & Functional Layer Compatibility

Engineered to bond functional layers like Nano-Ceramic Coated Aluminum Foil (0.05–0.2 mm), Glass Fiber-Reinforced Silicone Fireproof Cloth, and Carbonized Aramid Felt. It perfectly wets substrates including Aramid 1414 woven fabric, pre-oxidized knitted fabric, basalt fiber cloth, and stainless steel metal fiber blends.

5. Zero Toxic Gas Emissions

Ensures maximum safety during combustion. Toxic gas emissions are strictly limited to CO < 50 ppm and HCN = 0, fully complying with NFPA 1971 and far exceeding GB 8965.1 requirements.

Key Process Description

1. Heating & Application

The PUR hot melt adhesive is heated to the recommended temperature and applied precisely via roller coating or slot-die extrusion, adapting easily to high-performance fire-retardant substrates.

2. Rapid Barrier Integration

During the lamination process, it helps integrate the ceramic microsphere–aluminum foil composite layer rapidly, enabling the formation of a heat-reflective barrier within 0.3 seconds with >95% reflectivity (ASTM E424).

3. Moisture-Curing Action

Reacts chemically with ambient moisture over time to form a 3D cross-linked thermoset network. This prevents the adhesive from re-melting under extreme industrial heat or direct flame exposure.

Benefits in Protective & Industrial Apparel
