1.15g/Cm3 Automotive Hot Melt Adhesive Pur Hot Melt In Car Interior Lamination

PUR hot melt adhesive (Polyurethane Reactive Hot Melt Adhesive) is widely used in automotive interiors due to its high initial bonding strength, resistance to high/low temperatures, humidity and aging, and eco-friendly, solvent-free properties. It is particularly suitable for the diverse materials and complex operating conditions found in vehicles.

PUR hot melt adhesive is a reactive curing hot melt adhesive:

• First stage: Heated to about 100-140 °C, it melts and is applied to the substrate. After cooling, it quickly develops initial mechanical strength (thermoplastic stage).
• Second stage: It reacts with moisture in the air or in the substrates, forming a crosslinked polyurethane network and achieving final high strength and chemical resistance (reactive curing stage).
• This dual curing mechanism combines the fast initial tack of a hot melt with the long-term performance of a structural adhesive.

• Strong initial tack - parts can be handled and formed after cooling, without displacement.
• Wide temperature resistance - typically from -40 °C to 120 °C or higher, withstanding interior thermal cycles.
• Humidity and chemical resistance - passes 85 °C/85%RH high-temperature/humidity tests; resists aging, alcohol, and cleaning agents.
• Multi-substrate compatibility - good adhesion to PP, ABS, PVC, PU, fabric, leather (some low surface energy materials may require primer).
• Eco-friendly, low VOC - solvent-free, compliant with vehicle interior odor and VOC regulations.
• Good flexibility - remains elastic after curing to accommodate thermal expansion/contraction and vibration.

• Dashboard skin lamination (PVC/TPO film + foam + substrate)
• Door panel lamination (PU/PVC leather + foam + PP base)
• Headliner bonding (fabric + foam)
• Pillar trims, trunk trims, seat decoration parts, speaker covers
