For over two decades, Luyao has redefined precision bonding solutions as a leading hot melt supply company specializing in edge banding, furniture manufacturing, and industrial assembly. With 300+ global partners across 100 countries, our vertically integrated operations—spanning 100,000㎡ of production facilities—deliver 25 million meters of edge banding monthly, backed by ISO-certified R&D and REACH-compliant chemistries 710.
Why Hot Melt Adhesives Dominate Modern Manufacturing
Hot melts’ 100% solid formulation eliminates solvents, slashing VOC emissions by 95% versus traditional adhesives 1. Their rapid curing (2–25 seconds), thermal stability (-20°C to 120°C), and bond strength (≥8 N/mm²) make them indispensable for high-speed production. Luyao’s EVA-based granules achieve this while enabling:
- 30% faster line speeds in automated edge banding
- 18% energy savings via low-temperature processing (150°C–180°C) 5
- Zero stringing for defect-free furniture finishes

| Peel Strength | ≥8 N/mm² | ≥12 N/mm² | ≥7 N/mm² |
| Temp Resistance | -20°C to 95°C | -40°C to 160°C | -30°C to 110°C |
Precision Application Methodologies
A hot melt supply company’s value lies in optimizing application efficiency. Luyao’s adhesives integrate seamlessly with:
1. Automated Dispensing Systems
- Dot/Bead Application: Precision nozzles for minimal glue waste (0.2% overspray)
- Spray Systems: LVLP guns for uniform coating on contoured substrates 2
- Film Laminators: Pre-formed films for automotive/furniture veneers
2. Edge Banding Workflows
Luyao’s black EVA granules bond PVC bands to MDF/particleboard at 180°C–210°C, preventing “white edge” failures. Key protocols include:
- Surface Prep: Oil/dust removal to enhance bond strength by 50% 5
- Temp Control: ±5°C stability to avoid premature curing
- Adhesive Thickness: 0.1–0.3mm for “invisible” seams
