What is PUR?
Polyurethane Reactive Hot Melt Adhesive (PUR), is the moisture cured reactive polyurethane hot melt adhesive. The basis is end isocyanic acid polyurethane. Under the high temperature condition, PUR adhesive molecule react with the moisture in the air or on the adherend, or react with the live hydrogen matters to form portion cross-linked network structure, which makes the bonding strength, heat resistance, water resistance, chemical resistance better than other normal adhesives.
JCC5140 is tianyang most typical pur model for wood flooring, MDF board with PVC or CPL films, PVC board wrapping PVC films, acrylic sheet, veneer, PVC film, PET on PVC foam board,
MDF, plywood, particle ,matel, and other plastic boards, melting machine is PUR drum melter sysytem, and process by PVC wrapping and bending machine as below imagines show. For more details, please feel free to negotiate with us any times.
