Application of TPU Hot Melt Adhesive Film in Automotive Interiors: Selection Guide and Process Analysis
As automotive interiors evolve towards environmental sustainability, lightweight construction, and premium quality, TPU (Thermoplastic Polyurethane) hot melt adhesive film is increasingly replacing traditional solvent-based adhesives, becoming the preferred material for automotive interior lamination. This is due to its excellent properties: solvent-free, low VOC emissions, high bonding strength, and aging resistance. This article provides engineers with a comprehensive system for the selection and application of TPU hot melt adhesive film in automotive interiors, covering four key dimensions: material characteristics, application scenarios, critical selection factors, and process compatibility.
