O-rings are widely used in various industries for their ability to create a seal between two surfaces. The choice of O-ring material depends on the application and the environment it will be used in. Here are some common materials used for O-rings:
Nitrile (NBR): This is a popular material for O-rings due to its excellent resistance to oil, fuel, and water. It can withstand temperatures up to 100°C.
Viton (FKM): Viton is a fluorocarbon elastomer that has excellent chemical resistance, especially to high temperatures and harsh chemicals. It can withstand temperatures up to 200°C.
Silicone (VMQ): Silicone O-rings are known for their excellent flexibility and resistance to extreme temperatures, both high and low. They can withstand temperatures from -60°C to 200°C.
EPDM is a synthetic rubber that has excellent resistance to weather, ozone, and UV rays. It is commonly used in outdoor applications and can withstand temperatures up to 150°C.
Neoprene: Neoprene O-rings are known for their good resistance to oil, weather, and ozone. They can withstand temperatures up to 100°C.
