What are HNBR 70 Shore A Green Rubber O-Rings
HNBR 70 Shore A Green Rubber O-rings are a specific type of rubber O-ring made from HNBR (Hydrogenated Nitrile Butadiene Rubber) material. This O-ring seal has a hardness of 70 Shore A, a standard measurement scale used to determine the hardness of materials. They are commonly used in static and dynamic sealing applications, such as sealing liquids or gases. The characteristics of HNBR Rubber O-rings make them suitable for many sealing applications requiring high durability and reliability.

Advantages of HNBR 70 Shore A Green Rubber O-Rings
- Heat resistance: HNBR has excellent heat resistance and can maintain its physical and mechanical properties in high-temperature environments. This makes HNBR 70 Shore A Rubber O-rings suitable for high-temperature sealing applications.
- Oil resistance: HNBR has excellent oil resistance and can resist the erosion of various lubricants, fuels, and liquid chemicals. This makes HNBR Green Rubber O-rings excellent in applications involving liquid sealing.
- Chemical resistance: HNBR has good resistance to a variety of chemicals, including acids, bases, and solvents. This makes HNBR Rubber O-rings suitable for environments where resistance to chemical attack is required.
- High Hardness: The hardness of HNBR 70 Shore A means that this O-ring seal has certain stiffness and compression resistance. It provides a reliable seal and maintains shape and elasticity under pressure.
- High Mechanical Strength: HNBR 70 Shore A O-rings have high mechanical strength and can withstand large pressure and friction.
- Environmentally friendly: HNBR is an environmentally friendly material that meets environmental and health standards. It does not contain harmful substances such as halogen, sulfur, and lead and is safe to use.
