Advanced PUR hot melt adhesive systems have become the mainstream solution for laminating leather and fabric in automotive seat manufacturing. By balancing process efficiency, long-term durability, seating comfort, and environmental compliance, PUR technology plays a critical and irreplaceable role in modern automotive seating systems.
Features: excellent bonding strength, resistant for heat, chemical corrosion and aging, adjustable adhesion and flexibility
Process Flow
→ Preheating the foam (30–50 °C)
→ PUR hot melt adhesive application (roller, spray, or slot coating)
→ Placement of leather or fabric
→ Pressing and shaping
→ Cooling and initial processing
→ Moisture curing (final strength reached after approx. 24 hours)
- 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
Automotive Industry Trends and Technology Development
- Lightweighting: Low-density foams combined with high-performance PUR
- Process integration: Inline lamination to reduce process steps
- Sustainability: Bio-based PUR systems and compatibility with recyclable materials
- Smart manufacturing: Precision spraying and data-driven process control
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. Formulated PUR adhesives are solvent-free, low-VOC, and compliant with RoHS and REACH regulations.
Store in sealed containers, away from moisture and direct sunlight.
