PUR hot melt adhesives are transforming automotive interior manufacturing by delivering exceptional durability under extreme temperature fluctuations, humidity, and mechanical stress. These solvent-free bonding solutions comply with stringent environmental standards while offering manufacturers greater design freedom for integrating diverse materials like fabrics, foams, plastics, and composites.
PUR hot melt adhesive is a reactive curing hot melt adhesive with a dual curing mechanism:
- First stage: Heated to 100-140°C, it melts and is applied to the substrate. After cooling, it develops initial mechanical strength (thermoplastic stage).
- Second stage: Reacts with moisture to form a crosslinked polyurethane network, achieving final high strength and chemical resistance (reactive curing stage).
- Strong initial adhesion: Prevents composite material shifting during lamination
- Excellent flexibility: Maintains elasticity to accommodate cover deformation
- Superior heat resistance: Withstands -40°C to 120°C in-vehicle environments
- Heat/humidity resistance: Passes rigorous automotive testing standards
- Environmentally friendly: Low-VOC formulation meets automotive requirements
- Wide compatibility: Bonds effectively with fiberboard, porous substrates, and non-woven 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 |
| Acoustic Insulation | Felt/fiber pad mounting | Reduces glue usage 40% vs. spray adhesives |
Storage conditions: Sealed package, store in clean and dry place for 6 months.
Packaging: 20kg or 200kg barrels.
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, but surface treatment is usually necessary to ensure reliable bonding.
Yes. Properly formulated PUR adhesives are solvent-free and designed to meet strict automotive VOC/FOG/odor regulations.
