NBR (Nitrile Butadiene Rubber) rubber cord is a versatile sealing material known for its excellent resistance to oils, fuels, and chemicals. Here’s an overview of its features and applications:

1. Oil and Fuel Resistance: NBR rubber cord offers outstanding resistance to various oils, fuels, greases, and hydrocarbons. This makes it suitable for sealing applications in automotive systems, machinery, hydraulic systems, and fuel handling equipment.

2. Chemical Resistance: NBR rubber cord also exhibits good resistance to many chemicals, acids, and alkaline substances, enhancing its suitability for use in industries where exposure to chemicals is common.

3. Temperature Resistance: While not as high as some other elastomers, NBR rubber cord can withstand moderate temperatures, typically ranging from -40°C to 120°C (-40°F to 248°F). Special formulations may extend this temperature range further.

4. Compression Set Resistance: NBR rubber cord maintains its elasticity and sealing properties even after repeated compression cycles, thanks to its low compression set. This property ensures reliable sealing performance over time.

5. Water Resistance: While not as inherently waterproof as some other elastomers, NBR rubber cord can provide effective sealing against water and moisture ingress when properly designed and installed.

6. Mechanical Properties: NBR rubber cord offers good mechanical strength, tear resistance, and abrasion resistance, contributing to its durability and longevity in sealing applications.

7. Sealing Applications: NBR rubber cord is commonly used for sealing applications where resistance to oils, fuels, and chemicals is essential, such as gaskets, O-rings, seals, and washers in automotive, industrial, and marine environments.

8. Industrial Applications: NBR rubber cord finds applications in a wide range of industries, including automotive, oil and gas, machinery, construction, and agriculture, among others, where reliable sealing solutions are required.

9. Customization: NBR rubber cord is available in various diameters, hardness levels (durometer), and colors to meet specific application requirements. It can be easily cut, molded, or extruded to create custom seals and gaskets for different applications.

Overall, NBR rubber cord offers a cost-effective solution for sealing applications that demand resistance to oils, fuels, and chemicals, making it a popular choice across various industries.
