Automotive EVA Hot Melt Adhesive Web 80g/m² for Sun Visor Lamination with 74-100℃ Melt Range

EVA (Ethylene-Vinyl Acetate) mesh hot melt adhesive is a non-woven adhesive sheet that melts upon heating to create strong, flexible bonds between materials in automotive interior production.

1. Pre-cut layers: face fabric, foam, core
2. Layup: fabric / EVA web / foam → heated nip (130-145°C bondline, 8-12 seconds)
3. Second lamination: laminate to core with PO web
4. Cool & trim: maintain light pressure; die-cut openings
5. Edge wrapping & final forming: localized heating for turns; press in jig
6. Integration: mirror module, wiring, clips; functional checks

• Process latitude: bonds at low temperatures (110-150°C EVA; 120-170°C PO)
• Soft & breathable: maintains cushion feel and moisture transport
• Reactivation: heat allows re-positioning and repair before final assembly
• Cost-effective: lower cost than PA/TPU webs for similar lamination tasks

• Storage: cool, dry environment below 30°C; keep sealed to avoid dust pickup
• Shelf life: typically 12-24 months (check supplier COA)
• Safety: thermoplastic only—no solvents; avoid fumes from overheating; ensure guards on hot rollers/presses
• Traceability: track lot numbers through visor builds to correlate any field issues

What is EVA web hot melt adhesive? EVA (Ethylene-Vinyl Acetate) web hot melt adhesive is a non-woven mesh adhesive sheet that melts upon heating, creating strong and flexible bonds between materials. It is solvent-free, clean to handle, and easy to process in automotive interior production.

Can it bond to PP cores without treatment? Some EVA grades bond well directly to PP, but for best results (especially for high-temperature stability), a polyolefin web or surface treatment may be recommended for the foam-to-core layer.

Why is it suitable for sun visor bonding? It offers soft hand feel, good breathability, strong adhesion to foam, fabrics, and PP cores, plus resistance to temperature changes inside the vehicle. The web form also prevents visible glue lines or stiffness in laminated parts.
