PUR Hot Melt Glues: Revolutionizing Edge Banding for Furniture Manufacturing

When edge banding adhesive costs drop by ¥0.15 per meter, an automated production line processing 2 million meters annually saves ¥300,000. When edge banding failure rates plummet from 3% to 0.1%, customer complaints decrease by 90% – this is the tangible value PUR hot melt glue delivers to panel processors.

I. Solving 4 Critical Pain Points in Edge Banding

Pain Point	Traditional EVA Consequences	PUR Solution
Winter Debonding	＞8% failure at -5°C storage	95% bond retention at -40°C (7-day test)
Summer Softening	Edge bulging in ＞35°C workshops	120°C heat resistance (2.4× GB/T standard)
Visible Glue Lines	＞0.1mm seams require sanding	0.03mm ultra-thin bond line (visually undetectable)
VOC Emissions	Formaldehyde ＞0.2mg/m³	0 VOC (REACH Annex 17 certified)

II. Core Technology: Engineered for Panel Edge Banding

1. Low-Temp Application Technology

110-120°C application temp (vs. 170-190°C for EVA) → 40% energy reduction
90-second open time (3× longer than EVA) → Easy handling of complex profiles
Rheology index n=0.25 (vs. EVA’s 0.8) → Perfect wood pore filling

2. Molecular-Level Penetration

300μm penetration depth in oak/walnut (vs. ＜80μm for EVA)
＞8MPa shear strength (exceeds wood substrate strength)

3. Intelligent Stress Buffer

120MPa elastic modulus (vs. 400MPa for EVA) → Absorbs wood expansion stress
＜0.05mm edge displacement at 30-85% RH fluctuations
