What is NBR Rubber Cord?

NBR rubber cord, made from Nitrile Butadiene Rubber (NBR), is a synthetic rubber particularly well-suited for applications requiring resistance to oil and fuel. This material stands out for its high resistance to mineral oils, greases, hydraulic fluids, and many other chemicals, making it ideal for O-ring applications in various industrial sectors.

NBR rubber boasts excellent abrasion resistance and good mechanical properties, ensuring a long-lasting seal even in demanding environments. The temperature range of NBR typically lies between -30°C and +100°C, making it suitable for both low and moderately high temperatures. These properties make NBR rubber widely used in the automotive industry, hydraulic systems, and other applications where reliable sealing is crucial.

The Benefits of NBR Rubber Cord

NBR rubber cord offers a wide range of benefits that make it a popular choice for industrial sealing solutions. One of the key advantages is its excellent chemical resistance to oils, fuels, greases, and other industrial chemicals. Additionally, NBR rubber has a broad temperature range of -30°C to +100°C, ensuring reliable performance in both cold and moderately warm conditions.

Below is an overview of the key benefits:

Abrasion Resistance: Extended lifespan due to high wear resistance.
Flexibility: Remains flexible even at low temperatures, allowing adaptation to different surfaces.
Cost-Effective: An economical solution without compromising on quality.
Versatility: Suitable for a wide range of applications, from hydraulic systems to the automotive industry.

These characteristics make NBR rubber cord ideal for creating durable and reliable seals in various industrial environments.

Applications of NBR Rubber Cord

NBR rubber cord is widely used in various industries due to its excellent resistance to oils, greases, and chemicals. In hydraulic systems, it provides reliable seals that prevent leaks, even under high pressure. The automotive industry uses NBR O-rings for seals in engines, transmissions, and fuel systems, where durability and chemical resistance are crucial.

In the food industry, NBR rubber cord is used because of its safe interaction with oils and greases in equipment, although it is not suitable for direct food contact applications. Additionally, it is used in pneumatic systems and general mechanical engineering, where high abrasion resistance and flexibility are important. This versatility makes NBR rubber cord indispensable in a wide range of industrial applications.

Comparison with Other Materials

NBR rubber cord stands out for its excellent resistance to oils, greases, and fuels, but how does it compare to other materials such as EPDM, Viton, and silicone?

NBR vs. Viton: Viton offers higher temperature and chemical resistance than NBR, making it suitable for extreme conditions, but NBR is generally more affordable and better suited for low temperatures.

EPDM vs. NBR: EPDM is particularly resistant to ozone, UV radiation, and weather influences, making it suitable for outdoor applications, while NBR is preferred in environments where oils and fuels are present.

Silicone vs. NBR: Silicone is extremely flexible and performs well at very high and low temperatures, but has lower chemical resistance and abrasion resistance than NBR rubber cord, making it less suitable for industrial applications where oil resistance is essential.

Frequently Asked Questions

Below is an overview of the 10 most frequently asked questions about NBR rubber cord. If your question is not listed here, please feel free to contact one of our specialists.

1. What is NBR rubber cord and what is it used for?
NBR rubber cord is a sealing material made from Nitrile Butadiene Rubber (NBR). It is used to make O-rings that prevent leaks in hydraulic systems, fuel systems, and other industrial applications where oils and chemicals are present.

2. How do I choose the right size NBR rubber cord for my application?
The correct size of NBR rubber cord is determined by the diameter of the groove in which the O-ring is placed, as well as the required thickness of the cord. Ensure that the size accurately matches the specifications of the application to prevent leaks.

3. What temperatures can Nitrile rubber cord withstand?
Nitrile rubber cord can withstand temperatures from -30°C to +100°C, making it suitable for use in both cold and moderately warm environments.

4. Is NBR rubber cord resistant to chemicals and oils?
Yes, NBR rubber cord is particularly resistant to oils, fuels, greases, and many other industrial chemicals, making it ideal for environments where such substances are present.

5. How does NBR rubber cord differ from other materials like EPDM or Viton?
NBR is more resistant to oils and fuels, while EPDM performs better in environments with ozone, UV radiation, and weather influences. Viton offers higher chemical and temperature resistance than NBR, but is more expensive and less suitable for low temperatures.

6. Can NBR rubber cord be used in food processing equipment?
While NBR rubber cord is oil and grease-resistant, it is not always suitable for direct contact with food. For applications involving direct food contact, other materials like silicone are usually used.

7. How do I correctly install NBR rubber cord to prevent leaks?
Ensure that the cord is accurately cut to size and the ends fit well together. Use the appropriate O-ring adhesive to create a strong bond and avoid twisting during installation.

8. What are the benefits of gluing NBR rubber cord?
Gluing NBR rubber cord allows for the creation of custom-sized O-rings that perfectly fit specific sealing requirements, without long waiting times for special orders. Glued O-rings retain their durability and chemical resistance.

9. How do I maintain NBR rubber cord to extend its lifespan?
Maintain Nitrile cord by regularly inspecting it for wear, drying out, or cracking. Avoid exposure to extreme temperatures outside the recommended range and only use it with the correct chemicals to prevent degradation.

10. Where can I buy special adhesive for bonding NBR cord?
You can purchase special O-ring adhesive from us, specifically developed for bonding NBR cord. This adhesive provides a strong, seamless bond that withstands pressure and chemical influences.
