| Type | High Temp (°C) | Low Temp (°C) | General Properties |
|---|---|---|---|
| ACM | 150 | -10 | Used in diaphragms/hoses. Good resistance to heat, ozone, and oil. |
| NR | 70 | -40 | Excellent compression set, high tensile strength, and vibration dampening. |
| VMQ | 225 | 55 | Wide temperature range. Good weather/ozone resistance; poor mechanical properties. |
| PTFE | 250 | -150 | Low friction coefficient, used in seal lips. Poor elastic property. |
| TPU | 100 | -40 | Extreme mechanical properties, high abrasive and tear strength. |
| FKM | 200 | -25 | Excellent chemical resistance except for esters and ketones. |
| XNBR | 100 | -40 | Modified NBR with carboxyl groups. Better tensile strength and abrasion. |
