What is the difference between EVA and PUR edgebanding glue?

EVA (Ethylene Vinyl Acetate) and PUR (Polyurethane Reactive) are two different types of adhesives used in the production of edgebanding, which is applied to the edges of panels, such as those used in furniture manufacturing. Here are the key differences between EVA and PUR edgebanding glue:

EVA (Ethylene Vinyl Acetate) Edgebanding Glue:
Application:
EVA glue is applied in a hot-melt state during the edgebanding process. It is heated to a molten state, applied to the edge, and then solidifies as it cools.
Activation Temperature:
EVA adhesives have a relatively low activation temperature, typically ranging from around 150 to 180 degrees Celsius (302 to 356 degrees Fahrenheit).
Bonding Time:
EVA adhesive offers a fast bonding time. The bond is usually achieved quickly after application and cooling.
Workability:
EVA edgebanding is known for its ease of workability. It can be easily trimmed and processed after application.
Application Methods:
EVA is suitable for various application methods, including hot air, infrared, or laser application systems.
Color Clarity:
EVA adhesives generally provide good color clarity and transparency, which can be important when the edgebanding is applied to surfaces with visible colors or patterns.edge banding machine glue
PUR (Polyurethane Reactive) Edgebanding Glue:
Application:
PUR glue is applied in a liquid state and cures (reacts) over time. It does not require immediate cooling for bonding.
Activation Temperature:
PUR adhesives have a higher activation temperature compared to EVA, typically ranging from around 120 to 150 degrees Celsius (248 to 302 degrees Fahrenheit).
Bonding Time:
PUR adhesives offer a longer open time, allowing for extended bonding time. The curing process continues over hours or days, resulting in a strong and durable bond.
