NR-40 Grey Natural Rubber Membranes
NR-40 Grey is a highly elastic natural rubber membrane designed for vacuum pressing, veneering, laminating and woodworking applications. With a hardness of 40 Shore A and elongation of up to 700%, the membrane closely follows the contours of workpieces and distributes pressure evenly across the surface.

Features of NR-40 Grey Natural Rubber Membranes
- material: natural rubber;
- hardness: 40 Shore A;
- elongation: up to 700%;
- tensile strength: 20 MPa;
- operating temperature: up to 130 °C;
- available thicknesses: 2, 2.5, 3 and 4 mm;
- available widths: 1700 and 2000 mm, depending on the product;
- colour: grey.
The membrane can be used for both cold and heated pressing processes, including applications involving heat-activated adhesives. Its high elasticity makes it suitable for pressing shaped, curved and profiled components.
Recommended Applications
NR-40 Grey natural rubber membranes are suitable for:
- veneering flat and shaped components;
- laminating MDF, particleboard and other wood-based panels;
- manufacturing curved laminated components;
- pressing furniture fronts and interior elements;
- general vacuum bag and membrane press applications.
For processes that operate continuously at very high temperatures, a silicone membrane may be a more suitable choice. Natural rubber provides excellent elasticity and mechanical strength, but its temperature resistance is lower than that of silicone.
Available Sizes and Supply Options
NR-40 Grey membranes are available in thicknesses of 2, 2.5, 3 and 4 mm and in widths of 1700 and 2000 mm, depending on the product. They can be supplied in custom-cut lengths, complete rolls or sheets cut to fit specific vacuum presses.
Cut-to-size membranes are available for vacuum presses from manufacturers such as Adamik, Artex, Istra-A and Felder. Check the dimensions of your existing membrane or press frame before ordering. If you need help selecting the appropriate thickness or size, please contact us.
