What is HNBR?

HNBR is a synthetic elastomer that is derived from nitrile rubber (NBR). It is made by hydrogenating the double bonds in the butadiene portion of NBR, resulting in a polymer that has excellent resistance to heat, chemicals, and oils. HNBR is known for its ability to withstand high temperatures, ranging from -40°C to 150°C, making it a popular material for applications in automotive, industrial, and aerospace industries.

What does HNBR mean?

As mentioned earlier, HNBR stands for Hydrogenated Nitrile Butadiene Rubber. The hydrogenation process improves the properties of NBR, making it more suitable for high-temperature and high-pressure applications.

Physical and Mechanical properties

HNBR has impressive physical and mechanical properties that make it suitable for demanding applications. It has excellent resistance to compression set, which means that it can maintain its shape and performance even after being subjected to high pressures. HNBR also has good tensile strength, tear resistance, and abrasion resistance, making it durable and long-lasting.

Chemical and Temperature Resistance

One of the most significant advantages of HNBR is its excellent chemical resistance. It can resist exposure to a wide range of chemicals, including acids, bases, oils, and fuels. HNBR also has outstanding resistance to ozone and UV radiation, which makes it an ideal material for outdoor applications. In addition to its chemical resistance, HNBR also has exceptional temperature resistance. It can withstand temperatures ranging from -40°C to 150°C, making it suitable for use in applications that require high-temperature stability.
