Hydrogenated NBR is a tough, high-performance elastomer with excellent resistance to heat, chemicals, ozone and other harsh environmental factors. It is a hydrogenated version of Nitrile Butadiene Rubber (NBR), which is known for its oil resistance. However, hydrogenated NBR offers higher thermal stability, tensile strength, aging resistance, abrasion resistance and compression set than NBR.
In applications where O-rings need to withstand extreme temperatures and aggressive chemicals, Dawn HNBR for O-rings is the ideal choice.
Here are some advantages of using Dawn HNBR for O-rings:
1. High-temperature resistance:
Dawn HNBR for O-Rings has a superior heat resistance range of -40°C to +165°C, making it ideal for high-temperature applications. This property ensures that the O-ring maintains its sealing properties and does not crack or degrade due to thermal cycling.
2. Chemical resistance：
Dawn HNBR for O-Rings is resistant to a wide range of chemicals, including acids, alkalis, oils and solvents. It maintains sealing performance even when exposed to harsh chemical environments.
3. Excellent mechanical properties:
Dawn HNBR for O-Rings has higher tensile strength and elongation at break, making it less likely to tear, crack or deform. O-rings made from HNBR perform better and last longer.
4. Low compression set:
Dawn HNBR for O-Rings has good resistance to compression set, which means they retain their original shape and sealing properties after compression or deformation.
5. Aging resistance:
Dawn HNBR for O-Rings has excellent resistance to oxidation and ozone aging, ensuring that o-rings will not degrade or harden due to prolonged exposure to air, UV rays or ozone.
Overall, Dawn HNBR is an excellent choice for you looking to improve the performance and reliability of o-rings.
