Hot Melt Adhesive

Our hot melt adhesives are engineered for high-speed production, clean application, and reliable bonding across packaging, woodworking, textiles, automotive, electronics, and consumer product assembly. Formulated with EVA, PO, PA, PUR, and specialty polymers, they deliver fast setting, strong adhesion, and excellent thermal stability.

Key Technical Highlights:

Viscosity Range: ~800–50,000 cps (at 180°C, depending on grade)
Softening Point: ~70–160°C
Open Time: Short, medium, or long depending on application speed
Temperature Resistance: Typically -20°C to 80°C, PUR grades up to 120°C

These performance characteristics ensure consistent bonding efficiency across both automated and manual systems.

Frequently Asked Questions

EVA: General-purpose, cost-effective, widely used for packaging.
PO: Higher heat resistance and oxidation stability, ideal for demanding packaging and assembly.
PA: High-temperature and chemical resistance, suitable for electronics.
PUR: Moisture-curing with strong structural bonding and excellent durability.

The required temperature depends on the adhesive chemistry and viscosity. EVA grades typically run at 150–180°C, PO grades at 130–170°C, and PA adhesives at 180–220°C. PUR hot melts generally process at 110–140°C due to their reactive nature. Using a temperature too low may cause incomplete melting and poor wetting, while overheating can lead to oxidation, char formation, and viscosity drift. Equipment should be calibrated regularly to keep temperature within the recommended range.

Stringing and charring often result from excessive temperature or prolonged residence time in the melter. Maintaining stable operating temperatures, cleaning filters and nozzles routinely, and avoiding unnecessary heating cycles help minimize degradation. Choosing formulations with good thermal stability also significantly reduces carbonization and ensures smooth application, especially in long production runs.

Standard packaging-grade hot melts may become brittle or lose tack at temperatures below –10°C. For cold-chain packaging, winter logistics, or refrigerated storage, low-temperature-flexible grades—such as specialized EVA or polyolefin formulations—are recommended. These adhesives maintain elasticity and bond strength even during repeated thermal cycling.

Yes, but performance varies depending on the plastic type. Materials like PP, PE, and certain engineering plastics have low surface energy, which makes bonding challenging. Polyolefin hot melts and PUR hot melts typically provide better adhesion to these substrates. In critical applications, surface treatment or primer may be required to achieve optimal bonding strength.

Open time is determined by production speed, substrate absorbency, and the size of the bonding area. Short open-time formulations support fast automated lines such as carton sealing, while medium to long open-time adhesives are better suited for assembly, textiles, or foam lamination. Selecting the appropriate open time ensures adequate wetting before the adhesive solidifies, preventing weak or incomplete bonds.

Most hot melts bond well to clean and dry surfaces without additional treatment. However, contaminants such as oil, dust, and release agents significantly reduce adhesion, especially on plastics and metals. Wiping the substrate or using a light mechanical cleaning method ensures consistent bonding. Reactive PUR adhesives require especially dry surfaces, as moisture can prematurely cure the adhesive inside the equipment.

Hot melt adhesives should be stored in a cool, dry, and well-ventilated environment away from heat sources. For standard EVA, PO, and PA materials, sealed packaging prevents contamination. PUR hot melts must be kept in moisture-proof containers to avoid premature curing. Rotating inventory and using unopened packages promptly helps maintain consistent performance.
