Natural rubber membrane NR-40-2.5-1700

NR-40 Membrane — 2.5 mm Thickness for Woodworking and Furniture Production

The NR-40 rubber membrane with a thickness of 2.5 mm and a width of 1700 mm is a professional material produced through vulcanization of natural rubber. It is widely used in woodworking and furniture manufacturing. Designed for stable performance under load, it precisely follows the shape of the workpiece and ensures high-quality results during veneering, laminating, and covering various materials.

The 2.5 mm thickness is considered optimal in the professional vacuum pressing segment. This size is ideal for all internal millings: the membrane easily follows local recesses, evenly wraps complex zones, and provides tight adhesion even when working with fine reliefs or deep contours. Unlike thicker membranes that are less suitable for small millings, NR-40 rubber offers softness and precision, delivering a cleaner and more uniform result when forming cabinet fronts and decorative elements.

High-Quality Rubber — Excellent Elasticity

The membrane is made from high-quality natural rubber, providing elasticity up to 700%, high stretchability, and resistance to mechanical stress. With a hardness of 40 Shore A, the material performs softly without creases while still withstanding the tension that occurs during vacuum pressing. With a tensile strength of 20 MPa, NR-40 easily handles intensive work cycles, is suitable for multi-shift production, and offers a longer service life compared to silicone alternatives.

Operating Temperature and Smooth Surface

A high thermal resistance up to 130 °C makes NR-40 suitable for most operating modes of vacuum presses used in furniture and joinery production. The material maintains elasticity at elevated temperatures, withstands heating–cooling cycles, and retains its original properties for a long time.

The smooth grey surface ensures perfectly even pressing without marks or defects. With a universal width of 1700 mm, NR-40-2.5 fits most European vacuum presses, installs easily, and requires no additional preparation. The membrane is talc-treated, improving sliding and ensuring even pressure distribution across the entire surface — especially important for:

• veneering and plywooding;
• laminating decorative plastics;
• working with leather and paper finishes;
• producing complex-shaped elements, including custom designs.

Advantages of NR-40-2.5

• optimal 2.5 mm thickness for internal millings and small details;
• high elasticity and ability to accurately follow complex contours;
• resistance to elevated temperatures and mechanical loads;
• long service life and excellent durability;
• perfectly smooth surface for clean pressing results.

If you need a high-quality rubber membrane for a vacuum press designed for intensive use, the NR-40 membrane with a thickness of 2.5 mm is one of the best options. It is easy to work with, reliable, and consistently delivers high-quality processing regardless of shape complexity.
