Polyurethane membrane by Global Vacuum Presses

Product overview

What is a polyurethane membrane for vacuum presses?

The polyurethane membrane is a transparent, flexible membrane used in vacuum presses for veneering, laminating, vacuum bagging, and wood bending processes. Its transparency facilitates workpiece positioning and visual monitoring of the process, while its elasticity allows for uniform pressure distribution across veneers, curved panels, large molds, and laminated wood assemblies.
