Nitrile rubber has good self-expanding properties, abrasion resistance and hydrocarbon-resistant properties. It can be used as a general material for water, vacuum, acid, salt, alkali, grease, oil, butter, hydraulic oil, glycol, etc. Can not be used in places such as acetone, ketone, nitrate, and fluorinated hydrocarbons. |
| EPDM |
-40℃~135℃ Instant -50℃~150℃ |
Ethylene-propylene rubber is a good general-purpose synthetic rubber that can be used in hot water systems, beverages, dairy products, ketones, alcohols, nitrates, and glycerin, but not in hydrocarbon-based oils, inorganics, or solvents.

-35℃~100℃ Instant -40℃~125℃ |
Neoprene is used in media such as acids, oils, fats, butters and solvents and has good resistance to attack. |
| FKM |
-20℃~180℃
|
Fluororubber is a good hydrocarbon-resistant base oil, fluorinated hydrocarbon rubber for oily gas and other petroleum products. It is suitable for water, oil, air, acid and other media, but it can not be used for steam, hot water or thicker than 82 °C. Alkali system. |
| SR | -70℃~200℃ | Silicone rubber is resistant to high temperature, low temperature and stable chemical properties, and is widely used in industries such as strong acid, weak alkali and food. |
Special materials: carboxylated nitrile rubber, hydrogenated nitrile rubber, corrosion-resistant ethylene-propylene rubber, steam-resistant fluoroelastomer, chlorosulfonated polyethylene |
