The temperature range for rubber O-rings depends on the material they are made of.
Nitrile rubber O-rings can be used at a temperature of 100°C.
Ethylene propylene rubber O-rings can be used at a temperature of 130°C.
Fluorine rubber O-rings have a relatively higher temperature range and can reach 200°C.
TPU,CPU,and rubber-made O-rings have a working temperature range of-40°C to+80°C and a working pressure of≤32Mpa,and are suitable for general hydraulic cylinders and general equipment hydraulic cylinders.
Silicone O-rings have a temperature range of-43°C to 210°C and have excellent high-temperature and anti-static properties.
Full fluorinated ethylene propylene(FFKM)O-rings can withstand high temperatures up to 300°C and low temperatures down to-20°C.
Three-element ethylene propylene(EPDM)rubber O-rings have a general temperature range of-55°C to 125°C and can be up to 150°C with over-oxidized sulfation.
Chloroprene rubber(CR)O-rings have a general temperature range of-40°C to 100°C,and can be up to 125°C for short periods of time.
Butyl rubber(IIR)O-rings have a general temperature range of-50°C to 110°C.
Acetic acid polymer(ACM)rubber O-rings have a general temperature range of-15°C to 150°C,and can be up to 175°C for short periods of time,with special materials reaching-25°C.
Natural rubber(NR)O-rings deteriorate easily in air and become sticky when heated,expand and dissolve in mineral oil or gasoline,and are resistant to alkali but not strong acids.They are suitable for use in automotive brake fluid,ethanol,and other liqu In summary,the temperature range for O-rings varies greatly depending on the material used,and suitable materials can be found to meet various application requirements from low to high temperatures.
