NBR oil sealing components
Advantages
1. Excellent oil resistance: Exhibits good resistance to mineral oils, fuel oils, aromatic solvents, and other substances, making it suitable for oil-based system applications.
2. Low cost: Compared to materials like fluorocarbon rubber, nitrile rubber is more affordable, making it suitable for large-scale use.
3. Temperature Adaptability: Standard operating range is -40°C to 120°C, with some high-performance grades reaching 120°C.
4. Mechanical Properties: Good elasticity makes it suitable for static or low-motion sealing applications (e.g., solenoid valves, pneumatic components).
Disadvantages
1. Limited Heat Resistance: Prone to aging under prolonged high temperatures (>120°C), unsuitable for high-temperature environments.
2. Incompatibility with polar solvents: Exposure to ketones, esters, nitro compounds, etc., causes swelling or failure.
3. Poor dynamic sealing performance: Prone to wear in high-speed friction or reciprocating motion applications; requires modified materials (e.g., hydrogenated nitrile rubber) as substitutes.
4. Poor ozone resistance: Susceptible to cracking under prolonged exposure to ozone environments.
