Reactive PUR Hot Melt Adhesive for Automatic Mattress Laminating Machine Foam Bonding 20kg

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.
