Which type of synthetic rubber is known for its oil resistance?

Nitrile rubber is well-known for its exceptional oil resistance, making it an ideal choice for applications where exposure to oils and hydrocarbons is a concern. This synthetic rubber has a high level of resistance to fuels, lubricants, and other petroleum-based products. Its composition, which includes acrylonitrile, gives it the ability to withstand degrading effects from oil, ensuring durability in industrial environments or applications that require contact with oils.

Butyl rubber, while it has good resistance to gases and moisture, does not provide the same level of oil resistance as nitrile rubber. Neoprene rubber offers a balance of properties, including some oil resistance, but it is not as specialized in this area as nitrile. Hypalon, known for its chemical resistance and weatherability, does not specifically focus on oil resistance, which makes nitrile the superior choice for such applications.
