HNBR O-Ring Material Description

HNBR O-Ring Material DescriptionOn our site, you’ll find a wide range of O-rings, all of which are designed for different purposes and with a variety of materials. One of the most effective options for a variety of mechanical needs is the HNBR O-ring. Today we’re going to share what exactly this type of O-ring is and the material that it is made from, so that you can find out if it’s the right option for your needs. It’s a great air-resistant option that can be used instead of nitrile rubber O-rings and one that more companies are opting to use today. Find out more about our range of products here and how we can help you to enjoy more success within any of your mechanical applications with our help.

What is the HNBR O-Ring?

HNBR is short for hydrogenated nitrile. This type of O-ring comes in both metric and imperial options and aims to offer an air-resistant alternative to the standard nitrile rubber O-rings that are very commonly used. They are excellent for use within applications with high heat levels and ozone concerns, so you’ll find they can be used for endless types of mechanical applications. The HNBR O-ring material makes it very resistant to a wide range of concerns, so you’ll find they are one of the top O-ring options on the market today. On our site, you’ll find thousands of different O-rings to choose from. They can be used in almost any industry, including petrochemical, agriculture, automotive, and offshore drilling applications.

What is Hydrogenated Nitrile?

HNBR comes about as a result of the hydrogenation of nitrile. This means that it has excellent chemical resistance and physical strength, which is why companies opt to upgrade to HNBR O-rings. Oil resistance is another great benefit of HNBR O rings and will help to improve operations within a variety of industries. If you are working at high power levels, this is another reason that HNBR could be a good option for you. They can work at a temperature range of between -30°C and +170°C, which is incredibly competitive when compared to other options. The hardness range sits between 30 and 95, which is very impressive.

HNBR is also sometimes called saturated nitrite, which is made by putting hydrogen into nitrile. This means the hydrocarbon sequences within the elastomer are saturated, helping to offer an excellent compression set and abrasion resistance. You’ll also find they have good impact resistance, resilience, stream resilience, and gas permeability. The main reason why you might switch to this type of O-ring is to ensure you have more oil resistance. The automotive fuel handling and oil industries particularly benefit from this component.

Features of Hydrogenated Nitrite

This material is made from a synthetic polymer which can be created when the double bonds in nitrile=s butadiene segments with hydrogen. The process leaves you with a material that offers excellent heat and chemical resistance, as well as improved mechanical characteristics. They come in 70, 80, or 90-durometer options, so there are possibilities for any type of business operation. You’ll find that they can be used with a variety of oils, including fuel, vegetable oils, and salt solutions. Just make sure you still avoid strong acids, as they don’t work well with HNBR O-rings.
