High-Strength Oil-Resistant Medium-Saturation HNBR Synthetic Rubber

Product Overview: High-Strength Oil-Resistant Medium-Saturation HNBR Synthetic Rubber

Our Medium-Saturation HNBR Synthetic Rubber is engineered to deliver exceptional performance in oil-exposed and high-stress industrial environments. With a 34% acrylonitrile content, this hydrogenated nitrile rubber (HNBR) offers superior oil resistance while maintaining flexibility and durability, making it ideal for seals, gaskets, and components in harsh operating conditions.

Key Technical Specifications:  

- Acrylonitrile Content: 34% – Optimized for balanced oil resistance and low-temperature flexibility.

- Mooney Viscosity (ML 1+4 @125°C): 70-90 – Ensures excellent processability for molding and extrusion.

- Iodine Absorption Value: 11-22 – Reflects controlled medium saturation for enhanced chemical stability and aging resistance.

- Hardness: Adjustable range (e.g., 60-90 Shore A) to meet diverse application demands.

Performance Advantages:

- Superior Oil & Fuel Resistance: Withstands prolonged exposure to oils, greases, and hydrocarbon fluids (tested per ASTM D471).

- High Tensile Strength: Maintains structural integrity under dynamic loads and extreme pressures.

- Thermal Stability: Operates reliably in temperatures from -30°C to +150°C (-22°F to +302°F).

- Abrasion Resistance: Ideal for high-wear applications like rotating seals and hydraulic systems.

Applications:  

- Oil & Gas: Seals for pumps, valves, and downhole equipment.

- Automotive: Fuel system components, O-rings, and timing belts.

- Industrial Machinery: Gaskets, hoses, and custom-molded parts for chemical processing.

Why Choose Our HNBR?  

- Customizable Formulations: Tailor hardness, viscosity, and saturation levels for specific needs.

- Consistent Quality: Compliant with ISO 9001 and ASTM standards.

- Extended Service Life: Reduces downtime in critical oil-exposed environments.
