Moisture curing reactive polyurethane hot melt adhesive(PUR HOT MELT ADHESIVE), with properties of easy bonding operation, wide range of application, adjustable adhesion and flexibility (elasticity). It has excellent adhesion with wood, plastics, leather, fabrics, metals, rubber and other materials and has become one of the important varieties of adhesive industry.
Features: excellent bonding strength, resistant for heat, chemical corrosion and aging, adjustable adhesion and flexibility
- High initial strength: Fabric does not shift after lamination, suitable for assembly line operation
- Good flexibility: Retains elasticity after curing, adapting to deformation during trunk lid opening/closing
- Temperature resistance: Withstands in-vehicle environment from -40℃ to 120℃
- Humidity/aging resistance: Passes high-temperature/high-humidity and thermal cycling tests
- Eco-friendly, low VOC: Meets automotive interior FOG/VOC requirements
- Wide substrate compatibility: Bonds well with fiberboard, porous substrates, and nonwoven fabrics
| Component | PUR Function | Technical Benefit |
|---|---|---|
| Instrument Panels | Skin-to-foam bonding | Prevents delamination during airbag deployment |
| Door Panels | Vinyl/leather wrapping | Eliminates wrinkles; withstands 10+ years UV exposure |
| Headliners | Fabric-to-substrate lamination | 0.1mm ultra-thin glue lines maintain fabric drape |
| Seat Assembly | Foam-to-frame fixation | 50% faster curing vs. urethane foams (increased line speed) |
| Acoustic Insulation | Felt/fiber pad mounting | Reduces glue usage 40% vs. spray adhesives |
- Packaging: 20kg or 200kg barrels
- Store in sealed containers, away from moisture and direct sunlight
- Shelf life: 6-12 months depending on product
- Requires specialized melters and dispensing systems designed for PU
PUR (Polyurethane Reactive) hot melt adhesive is a reactive curing adhesive. It first bonds like a thermoplastic hot melt when cooled, then chemically reacts with ambient moisture to form a crosslinked polyurethane network.
Yes, PUR hot melts are formulated to comply with stringent automotive VOC, fogging, and odor regulations.
Store in sealed containers, away from moisture and direct sunlight.
