MATERIAL | TEMP | ADANTAGES | LIMITATION |
Nitrile Rubbrt (NBR) | -40~125℃ | ■Good oil and fuel resistance■High tensile strength ■Low swelling in water | ■Poor weather and ozine resistance■Poor resistance against polar lkuids ■Poor resistance against clhydrocarbon ■Poor resistance against aromatic fluids |
Fluorinated Rubber (FKM) | -20~250℃ | ■The resistance against oil and fuels is better than other types■The only highly elastic rubber whice is resistance to aromatci and chlornated hydrocarbons ■Exccllcent hcat resistance ■Exccllcent weather and ozonc resistance ■Exccllcent acid resistance ■Low swelling in water | ■Limited cold flexibliity■Limited tensile and tear strength ■Limited wear resistance ■High compression set in hot water ■Poor resistance to polaric solvents |
Polyacrylate Rubber (ACM) | -25~150℃ | ■Good oil and fuels resistance■Good weater and ozone resistance | ■Not usable in contact with water and water solutions ■Limited cold flexibility ■Limited tensile strength and tear resistance ■Poor wear reisistance ■Poor resistance against polar and aromatic and chlorinared hydrocarhons |
Silicone Rubber (VQM) | -60~225℃ | ■Best heat resistance of all rubber types ■Excellent low temp resistance of all rubber types ■Excellent weather and ozone resistance | ■Poor tensile and tear strength ■Poor wear resistance ■Sensitive to hydrolysis ■Poor resistance against aromatic oils and oxidized mineral oils ■Poor diffusion resistance |
