Polyurethane Reactive (PUR) adhesive melting systems — from 5-gallon applicators to 55-gallon industrial drum machines with PLC nitrogen protection.
PUR (Polyurethane Reactive) hot melt adhesive cures through moisture in the air, creating bonds 5–10× stronger than standard EVA hot melt. It is the preferred adhesive for edge banding, bookbinding, automotive and high-performance lamination.
All Liujiang PUR machines feature nitrogen blanketing to prevent premature curing inside the tank, precision gear or piston pumps, and closed heated hose systems.
From compact 5-gallon edge banding units to full 55-gallon production drum systems.
Liujiang PUR machines work seamlessly with leading nozzle brands, reducing your retrofit costs.
Supports NI120 / NTC / K-type / PT100 sensors
