| Comparison Table of Common Oil Seal Material Characteristics |
| Material properties | NBR | ACM | MVQ | FKM |
| Oil resistance | Resistant to mineral oils and animal/vegetable oils, but not resistant to aromatic hydrocarbon oils. | It is resistant to mineral oils and lubricants, and its fuel resistance is superior to NBR. | Resistant to vegetable and animal oils, and silicone oil; not resistant to mineral oil. | Excellent performance, resistant to mineral oils, aromatic oils, strong acids, and strong alkalis. |
| Temperature resistance range | -40℃ to 120℃, and can reach 150℃ for short periods. | -20℃ to 170℃, and can reach 200℃ for short periods. | -60℃ to 200℃, and up to 250℃ for short periods. | -20℃ to 200℃, special grades can reach 250℃. |
| Chemical resistance | Resistant to weak acids and bases, but not resistant to strong acids, ketones, or esters. | Resistant to acids, alkalis, and oxidizing agents, but not resistant to ketones and esters. | Resistant to weak acids and bases, and ozone; not resistant to oils and solvents. | Resistant to strong acids, strong bases, strong oxidizing agents, and most organic solvents. |
| Physical properties | High tensile strength, good wear resistance, and excellent elasticity. | It has good wear resistance, and its resistance to compression set is superior to NBR. | Excellent elasticity, outstanding cold resistance, but poor wear resistance. | It has good tensile strength and excellent resistance to compression set. |
| Weather resistance | Ozone resistance is generally poor; protective agents need to be added. | It has good ozone resistance and aging resistance. | Excellent resistance to ozone, ultraviolet radiation, and aging. | Excellent resistance to ozone, aging, and weathering. |
| Applicable scenarios | Ozone resistance is generally poor; protective agents need to be added. | Automotive engine oil seals, fuel system seals, high-temperature seals | Low-temperature sealing applications, seals for food and pharmaceutical equipment, and insulation seals. | High-temperature and high-pressure seals, chemical equipment seals, and automotive oil seals for extreme operating conditions. |
