HNBR O-rings
HNBR stands for Hydrogenated Nitrile Butadiene Rubber. It’s a synthetic rubber compound noted for its excellent resistance to heat, oil, and various chemicals. O-rings made from HNBR are particularly popular in industries like automotive, aerospace, and oil & gas, where they are exposed to harsh environments. They offer better performance in terms of temperature resistance and chemical compatibility compared to traditional Nitrile Rubber (NBR) O-rings. These properties make them suitable for applications where standard NBR O-rings might degrade quickly due to exposure to heat, oil, or other chemicals.
O-rings HNBR - 70 Shore A
O-rings made from HNBR with a Shore A hardness of 70 are designed to provide a balance between flexibility and rigidity. The Shore A hardness scale measures the hardness of elastomers like rubber. A value of 70 indicates that the material has moderate hardness and can withstand a certain amount of deformation under pressure while still maintaining its shape and sealing properties.
HNBR O-rings with a Shore A hardness of 70 are commonly used in various industrial applications where they need to seal against fluids, withstand moderate pressures, and operate within a specific temperature range. The hydrogenation process in HNBR improves its resistance to heat, oil, and chemicals compared to standard NBR O-rings, making them suitable for more demanding environments.
O-rings HNBR - 80 Shore A
O-rings made from HNBR with a Shore A hardness of 80 are designed to be slightly harder and more rigid compared to those with a lower Shore A value, such as 70. The Shore A hardness scale measures the hardness of elastomers like rubber, with higher values indicating greater hardness.
HNBR O-rings with a Shore A hardness of 80 are suitable for applications where a tighter seal or greater resistance to deformation under pressure is required. The higher hardness level provides improved resistance to compression set, meaning they are less likely to lose their shape and sealing properties over time, especially when subjected to higher pressures or temperature fluctuations.
These O-rings are commonly used in demanding industrial environments where they need to seal against aggressive fluids, withstand higher pressures, and operate within a wide temperature range. The hydrogenation process in HNBR enhances its resistance to heat, oil, and chemicals, making it well-suited for such applications.
O-rings HNBR - 90 Shore A
O-rings made from HNBR with a Shore A hardness of 90 are even harder and more rigid compared to those with lower Shore A values, such as 70 or 80. The Shore A hardness scale measures the hardness of elastomers like rubber, with higher values indicating greater hardness.
HNBR O-rings with a Shore A hardness of 90 are suitable for applications where an extremely tight seal or exceptional resistance to deformation under pressure is required. The higher hardness level provides superior resistance to compression set, meaning they are highly resistant to losing their shape and sealing properties over time, especially when subjected to high pressures or temperature variations.
These O-rings are commonly used in demanding industrial environments where they need to seal against aggressive fluids, withstand very high pressures, and operate within a wide temperature range. The hydrogenation process in HNBR enhances its resistance to heat, oil, and chemicals, making it well-suited for such rigorous applications.
