Rubber membrane NR-40-Gray

The NR 40 Grey natural rubber membrane stands out in the market as a top-tier, 40 Shore A hardness rubber sheet characterized by its distinctive grey color and smooth texture. This membrane is engineered to perform under demanding conditions, withstanding temperatures as high as 130°C. Its remarkable elasticity allows it to stretch by up to 700%, a feature that significantly contributes to its longevity and reliability in various applications, thereby minimizing the frequency and costs associated with maintenance and replacements.

Boasting an exceptional tear strength of up to 60 N/mm, the NR 40 Grey membrane is particularly suited for challenging environments, such as those encountered in membrane vacuum presses used extensively in the woodworking and furniture manufacturing industries. This capability ensures that the membrane can withstand the rigors of continuous operation without succumbing to wear and tear easily, making it a valuable asset for businesses looking to optimize their production processes.

The versatility of the NR 40 Grey is further enhanced by its availability in multiple thicknesses, ranging from 2 mm to 4 mm, catering to a wide array of application requirements. Additionally, with widths available up to 2000 mm, it offers considerable flexibility for various equipment sizes and operational needs.

Manufactured in Europe, the NR 40 Grey elastomer membrane is a product of advanced material science and manufacturing processes, adhering to stringent European quality and safety standards. This European provenance not only assures users of its superior quality but also supports industries in maintaining high standards in their production lines.

In summary, the NR 40 Grey natural rubber membrane is an indispensable component for industries that demand high-performance materials capable of enduring extreme conditions while maintaining efficiency and productivity. Its combination of durability, flexibility, and high tear resistance makes it an ideal choice for businesses aiming to achieve excellence in their operations.
