EVA based hot melt adhesive
Crafted for automated edgebanding processes, this premium hot melt adhesive utilizes ethylene-vinyl acetate (EVA) as its core material, enhanced with advanced modification technology. It delivers rapid curing, exceptional temperature resistance (-20°C to 120°C), and zero VOC emissions, aligning with EU environmental standards. Ideal for bonding PVC, ABS, and other edgebanding materials in furniture, cabinetry, and decorative panel production, it seamlessly integrates with Homag, Biesse, and other automated edgebanders, boosting production line efficiency to over 22m/min. REACH-certified, it meets the global demand for sustainable manufacturing practices.
EVA Based Hot Melt Adhesive Benefits
- 3-Second Instant Bonding
A low melt-viscosity formula (12,000±500 mPa·s at 180°C) and 15-25 second open time optimize high-speed production, reducing downtime and increasing output by 30%. - Eco-Safe Composition
Solvent-free, formaldehyde-free, and VOC emissions below 0.1%, verified by SGS for food-grade packaging and medical device applications. - Superior Weather Resistance
Maintains over 95% bond strength in 90% humidity environments, ideal for Southeast Asia, Northern Europe, and other climate-sensitive regions. - Broad Compatibility
Customizable with flame-retardant (UL94 V-0) or UV-resistant additives for automotive interiors, electronics, and specialized industrial uses.

FAQs
Q: How to prevent summer oxidation yellowing?
A: Use antioxidant-enhanced variants (e.g., Irganox 1010) or add 0.5% UV absorbers (e.g., Tinuvin 326).
Q: Do you offer small-batch samples?
A: Yes – request a 1kg free sample with on-site engineer support for machine calibration.
Q: Is reworking possible?
A: Adhesive softens at 150°C for residue-free removal, ideal for repairs.
