NBR O-Ring Advantages & Disadvantages | Silicone Sealing Mold Manufacturing
When manufacturing silicone seal molds and rubber sealing products, NBR O-rings remain the most widely used sealing element. Let’s break down the main advantages and limitations of nitrile rubber O-rings.
Advantages of NBR O-Rings
- NBR O-rings deliver outstanding resistance to water, solvents and mineral oil, plus excellent air tightness for hydraulic and plumbing systems.
- Nitrile rubber features great wear resistance and reliable compression set performance under long-term clamping pressure.
Disadvantages of NBR O-Rings
- NBR seals cannot work well in polar chemical environments. They degrade quickly when exposed to ozone, ketones and other strong polar media.
