Black HNBR 90 Shore A O-Rings

About Black HNBR 90 Shore A O-Rings

Black HNBR 90 Shore A O-Rings are a special type of O-ring made from high performance black hydrogenated nitrile rubber (HNBR). These O-rings feature a 90 Shore A hardness elastomer and are typically used in applications requiring high resistance to wear, oil, and chemicals. This hardness gives the O-ring a certain degree of stiffness and resistance to compression deformation, making it suitable for applications requiring higher sealing performance.

Material characteristics

HNBR benefits:
• Resistant to mineral oil-based hydraulic fluids

• Resistant to new organic oils (organic oils)
• Suitable for high dynamic loads and has good wear resistance
• Suitable for temperatures from -30 degrees C to +150 degrees C
• Mechanically strong
• Good compression set / good “hot tear” / good ozone and aging resistance
• Resistant to high-energy radioactive radiation
• Good resistance to hot water and steam
• Temperature resistance to prolonged +150 degrees C with higher peaks
• Good resistance to various media
• Excellent heat and oxidation resistance
• Can be used in water and steam
• Temperature ranges from -30 degrees to +160 degrees C
• Excellent resistance to automotive fluids (engine oil, coolant, fuel, etc.)

Cons HNBR:
• Considerably more expensive

• Not resistant to polar solvents (ketones, eaters and esters)
• Not resistant to strong acids

Physical property information

Application

1. Industrial equipment: HNBR O-Rings are used in various industrial equipment. They can be used in equipment such as pipes, valves, pumps and pressure vessels to seal gases or liquids. Due to its resistance to chemicals and abrasion, it can be used in environments such as chemical plants, the oil and gas industry, and food processing plants.

2. Food and pharmaceutical industry: HNBR O-Rings are also suitable for applications in the food and pharmaceutical industry. These seals comply with food safety standards and can be used to seal food processing equipment, pharmaceutical production equipment and fluid transfer systems.

3. Medical equipment: HNBR O-Rings are also commonly used in medical equipment. They can be used to seal liquids and gases in medical devices, instruments and equipment such as infusion pumps, blood separators, ventilators, etc.

4. Petroleum and chemical industry: HNBR 90 Shore A O-Rings can be used to seal various petroleum and chemicals, such as oil, fuel, solvent, acid, alkali, etc., providing reliable sealing effect and preventing leakage and pollution.

5. Automobile industry: HNBR 90 O-Rings can be used for sealing of automobile engines, fuel systems, brake systems, cooling systems and other parts, providing good oil resistance and high temperature resistance to ensure the normal operation and safety of automobiles.

6. Aerospace industry: HNBR 90 O-Rings can be used for sealing and fluid control in the aerospace field, such as aircraft engines, hydraulic systems, fuel systems, etc., and can maintain good performance in extreme environments such as high temperature, high pressure, and high vacuum. .

7. Ship industry: Black HNBR 90 Rubber O-Rings can be used for sealing and fluid control of ships, such as engines, hydraulic systems, cooling systems, etc., and can withstand the effects of corrosion and salt spray in the marine environment.

Overall, Black HNBR 90 Shore A O-Rings have a wide range of applications and are suitable for use in areas as diverse as the automotive industry, industrial equipment, food and pharmaceutical industries, and medical equipment. Their resistance to chemicals, abrasion and temperature makes them a reliable sealing material.
