Product Overview

PUR hot melt adhesives are transforming automotive interior manufacturing by delivering exceptional durability under extreme temperature fluctuations, humidity, and mechanical stress. As the EV market emphasizes lightweight construction and energy efficiency, PUR hot melts reduce weight without compromising structural integrity or comfort. Their compatibility with recycling and circular economy initiatives makes them a cornerstone technology for sustainable, high-performance automotive interiors.

Application Process
Preheat substrate (if necessary) - ensures more uniform bonding
Apply PUR hot melt adhesive (roller, spray, or spread coating, at 110-140℃)
Lay nonwoven fabric - mechanical pressing or vacuum forming
Cooling and shaping - parts can be handled within a short time
Moisture curing - final strength achieved within 24h
Key Features & Benefits
  • 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
Automotive Applications
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 & Storage
  • 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
Frequently Asked Questions
What is PUR hot melt adhesive?

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.

Why is it used in car seat assembly?

In car seat assembly, it ensures strong, durable bonds between fabrics, leather, foam, and structural components, even under heavy use and extreme conditions.

What are the limitations of PUR adhesives in seat assembly?

Sensitive to moisture during storage (must be sealed tightly); Short open time requires precise process control.
