XNBR: Properties and Applications of a High-Performance Synthetic Rubber

XNBR (Carboxylated Nitrile Rubber) is a synthetic elastomer material that has excellent resistance to oil, heat, and abrasion. XNBR rubber is a type of Nitrile rubber that has been modified by introducing carboxyl groups into the polymer chain. This modification results in a material that has improved tensile strength, abrasion resistance, and chemical resistance compared to traditional Nitrile rubber. This makes XNBR well suited for a wide variety of applications, including many dynamic applications. The added strength and abrasion resistance of XNBR make these seals popular for reciprocating parts in heavy industrial applications. In this blog, we will take a closer look at XNBR rubber and its various applications. If you’re interested in learning more, see our XNBR page.

Properties of XNBR Rubber

XNBR rubber has several unique properties that make it an ideal material for a wide range of applications, including:

1. Improved Tensile Strength: The introduction of carboxyl groups into the polymer chain results in improved tensile strength compared to traditional Nitrile rubber.
2. Excellent Abrasion Resistance: XNBR rubber has excellent abrasion resistance, making it an ideal material for use in applications that require resistance to wear and tear.
3. Good Chemical Resistance: XNBR rubber has good resistance to many chemicals, including oils and solvents. It also has good resistance to many diluted acids and bases.
4. Extended temperature range compared to traditional Nitrile.
5. Resistance to refrigerants: R-11, R-12, R-13.
6. Available in multiple compounds to meet performance and cost requirements.

Limitations of XNBR Rubber

XNBR rubber has limitations that should always be taken into account for specific types of applications:

1. Poor resistance to ozone, direct sunlight, UV, and weathering.
2. Poor resistance to aromatic fuels, glycol-based brake fluids, polar solvents, non-flammable hydraulic fluids (HFD), aromatic/chlorinated hydrocarbons, ketones, esters, and aldehydes.
3. Service Temperature Range (varies with application): -20°F to 302°F ( -30°C to 150°C).

Applications of XNBR Rubber

XNBR rubber has a broad range of applications across various industries, including:

1. Automotive: XNBR rubber is widely used in the automotive industry for manufacturing seals, gaskets, and other components that require resistance to oil and abrasion.
2. Oil and Gas: XNBR rubber is used in the oil and gas industry for manufacturing seals, gaskets, and other components that require resistance to oil and abrasion.
3. Industrial: XNBR rubber is used in the industrial applications for manufacturing seals, gaskets, and other components that require resistance to oil and abrasion.
4. Consumer Goods: XNBR rubber is used in the consumer goods industry for manufacturing products that require resistance to oil and abrasion, such as hoses and belts.

Conclusion

XNBR rubber is a highly versatile elastomer material that offers excellent resistance to oil, heat, and abrasion. Its unique properties make it an ideal material for a wide range of applications across various industries, including the automotive, oil and gas, industrial, and consumer goods industries. If you require a material that offers excellent resistance to oil and abrasion for your industrial application, XNBR rubber may be an excellent choice for you.
