They serve a wide range of industries, from automotive to food processing, making them an adaptable solution.
Applications of NBR Gaskets
NBR Gaskets are incredibly versatile, finding use across various sectors where resistance to oils, fuels, and chemicals is essential.
Common Challenges of NBR Gaskets
While NBR Gaskets offer many benefits, they also have limitations that should be considered:
- Temperature Range Limitations:
NBR Gaskets may not perform well in extremely high or low temperatures, limiting their use in environments beyond -40°C to 120°C. - Ozone and UV Sensitivity:
NBR is prone to degradation when exposed to UV light or ozone, making it less suitable for outdoor applications without protective coatings. - Chemical Compatibility:
NBR Gaskets may not be resistant to certain harsh chemicals, such as strong acids, ketones, or solvents like acetone. - Pressure Handling:
In high-pressure systems, NBR Gaskets may compress or deform over time, especially in extreme conditions. - Swelling in Some Fluids:
NBR can absorb certain fluids, leading to swelling, which may compromise the Gasket’s ability to maintain a tight seal. - Low Flexibility at Low Temperatures:
At extremely low temperatures, NBR can become brittle and lose its flexibility. - Electrical Insulation:
NBR Gaskets have limited electrical insulation properties, making them unsuitable for applications where dielectric strength is required. - Ageing and Deterioration:
Over time, NBR can harden and lose its sealing effectiveness, especially in extreme environments.
Industry-Specific Materials for Gaskets
Different industries use a variety of materials based on their specific operational demands.
These include:
- Automotive: NBR, EPDM, Viton® for oil and fuel systems.
- Oil and Gas: NBR, PTFE, and metallic Gaskets for pipelines and valves.
- Aerospace: Viton®, silicone, and PTFE for fuel and hydraulic systems.
- Chemical Processing: PTFE and Viton®, for aggressive chemicals.
- Food & Beverage: Food-grade NBR, silicone, and EPDM for processing machinery.
- Water Treatment: EPDM and NBR for hydraulic systems in treatment plants.
