Performance and Selecetion Key Points for Hot Melt Glue for Automotive Interior Bonding

1. Heat resistance

For components such as headliners and door panel seals that must withstand high vehicle temperatures (up to 105℃), PO/PA hot melt glue or PUR hot melt glue are recommended.

2. Flexibility and resilience

For coverings requiring a high tactile feel (such as headliners and soft-touch panels), EVA hot melt glue or modified PO is required to ensure softness and resist cracking.

3. Aging and UV resistance

For interiors exposed to long-term light adn heat cycles, PUR hot melt glue and PA hot melt glye offer the best long-term performance.

4. Low odor and low volatility

For automotive interiors with stringent requirements for volatile organic compounds (VOCs) and odor, low-VOC PO hot melt glye or formaldehyde-free EVA hot melt glue are more suitable.

5. Automation compatibility

All systems must meet the requirements for quick-drying (opening time <3 seconds) during spraying/applying to accommodate high speed dispensing and lamination cycles in the workshop.

Hot Melt Glue Production Line and Process Key Points

  • Mixing and filtration: Reactor or sigma mixer ensure uniform, particle-free mixing, high temperature filters remove impurities.
  • Temperature control and melting: PID temperature control coils or thermal oil jackets ensure strict temperature control (±1℃) to prevent degradation and overheating.
  • Degassing: PUR hot melt glye requires vacuum degassing before extrusion to prevent solidification bubbles.
  • Packaging and storage: Hot melt glue is typically available in granules or sticks. Granular hot melt glue is suitable for automatic dispensing machines, while sticks are suitable for handheld hot glue guns.

 

With the rapid development of the automotive industry and the increasing global demand for lightweight, environmentally friendly, and efficient automotive manufacturing technologies, the application of hot melt glue in the bonding of automotive interior components has also gradually expanded. Whether bonding door panels, ceilings, instrument panels, carpets, or fabrics, foam, or plastic parts, hot melt glue have become a widely adopted adhesive solution by automakers due to their excellent adhesion, fast curing, and environmental performance.
