PUR Hot Melt Adhesive Reactive PU Hot Melt Glue for Automatic Mattress Laminating Machine Foam Bonding

This reactive PUR hot melt adhesive, also known as reactive PU hot melt glue, is tailor-made to match automatic mattress laminating machines and dedicated for foam bonding processes in mattress manufacturing. Featuring stable melting viscosity, controllable open time and excellent fluidity during continuous high-speed coating, it delivers uniform glue application without wire drawing or carbonization inside machine nozzles. After moisture cross-linking, the adhesive forms flexible, irreversible chemical bonds between PU foam, fabric ticking, felt and pocket spring components, offering outstanding peel resistance, anti-aging performance and stable adhesion even after long-term mattress compression and rolling. Completely solvent-free and low-odor, it meets furniture eco-friendly standards, effectively reducing defective delamination products and greatly lifting the operating efficiency of full-automatic mattress lamination production lines.

Key Features and Benefits

1. Superior Bonding Performance for Mattress Foam

   • High initial tack plus ultimate peel strength: Fast sticks sponge, mattress fabric, non-woven fabric and pocket spring frames, no separation during mattress rolling, compression and packaging.
   • Moisture crosslinking curing mechanism: Forms permanent elastic chemical bonds after full reaction, never remelts under high temperature, far better anti-delamination than ordinary EVA hot melt.
   • Great material compatibility: Perfectly bonds all common mattress raw materials including PU foam, memory foam, knitted ticking and fiber felt.

   2. Optimized Processing for Automatic Laminating Machines

   • Stable melting viscosity with moderate open time, perfectly fit high-speed full-automatic mattress laminating production lines.
   • Excellent thermal stability, no carbonization, no stringing or clogging machine nozzles during long continuous heating, cutting equipment cleaning downtime.
   • Smooth thin coating without penetrating soft foam and thin fabrics, keeping mattress surface soft without hard glue spots.
   • Single-side gluing process reduces glue consumption, shortens assembly waiting time and boosts factory output.

   3. Long-lasting Durability

   • Excellent heat, moisture and aging resistance. No yellowing, cracking or adhesion failure under long-term bedroom humid environment.
   • Cured glue layer maintains consistent flexibility, resists repeated long-term extrusion load, ensures mattress structural stability for years.

   4. Eco-friendly & Safe Formula

   • 100% solid content, solvent-free, zero VOC and formaldehyde, low odor during production.
   • Complies with international furniture and textile environmental standards, safe for direct human contact mattresses.

   5. Stable Cost Control

   • Consistent batch quality with long shelf life for unopened barrels, less waste caused by glue deterioration.
   • Low reject rate of delaminated finished mattresses, comprehensively lowering overall production cost for mattress manufacturers.
