Industrial Grade PUR Reactive Hot Melt Glue Polyurethane Adhesive for Mattress Sponge Textile Lamination Pocket Spring Mattress Bonding

Our industrial grade PUR reactive hot melt glue is a high-performance polyurethane adhesive specially engineered for mattress manufacturing, sponge composite and textile lamination processes. Featuring stable open time, strong initial tack and outstanding permanent bonding strength, this PU hot melt adhesive works perfectly for pocket spring mattress assembly, firmly bonding foam sponge, knitted fabrics, non-woven layers and spring frame components together. The reactive cross-linking structure delivers excellent resistance to heat, humidity and aging, preventing delamination or peeling even after long-term mattress compression and daily use. Free of solvent and low in odor, it meets modern furniture environmental standards, suitable for continuous automatic laminating production lines as well as manual mattress bonding operations, greatly improving production efficiency and the overall durability of finished pocket spring mattresses.

Key Features and Benefits

1. Bonding Performance

   • High initial tack & ultimate peel strength: Quickly adheres sponge, textile fabric, nonwoven and pocket spring frames, no rebound separation during mattress compression and packaging.
   • Reactive crosslinking curing: Forms irreversible chemical bonds after moisture reaction, far stronger than ordinary EVA hot melt, anti-delamination for long service life.
   • Excellent compatibility: Perfect lamination for all common mattress materials—polyurethane sponge, knitted cloth, felt, spring metal accessories.

   2. Environmental & Safety Edges

   • 100% solvent-free, no formaldehyde, low odor during production, complies with furniture textile eco standards.
   • No volatile toxic substances, meets indoor mattress environmental requirements, safe for finished products contact with human body.

   3. Production Processing Advantages

   • Stable viscosity and moderate open time, adaptable to high-speed automatic laminating machines and manual gluing equipment.
   • Good heat stability with no carbonization or wire drawing under continuous heating, reduces machine cleaning frequency and downtime loss.
   • Uniform coating without penetration into thin fabrics, avoids hard spots, maintains soft touch of mattress surface.

   4. Durability & Weather Resistance

   • Outstanding anti-aging, heat resistance and moisture resistance. Won’t turn yellow, crack or lose viscosity under high temperature storage or humid bedroom environment.
   • Resists repeated extrusion and long-term load bearing, ideal for pocket spring mattresses that require long-term structural stability.

   5. Cost & Efficiency Benefits

   • Single-side gluing process saves glue consumption vs water-based adhesives.
   • Fast curing speed shortens assembly waiting time, boosts mattress production line output significantly.
   • Long shelf life of glue granules, stable batch quality, reduces waste caused by glue deterioration.
