| Type | High Temp (°C) | Low Temp (°C) | Properties |
|---|---|---|---|
| ACM | 150 | -10 | Good resistance to heat, ozone, and oil. Used in diaphragms and hoses. |
| NR | 70 | -40 | High tensile strength, resilience, and excellent vibration dampening. |
| VMQ | 225 | 55 | Widest temperature range. Good weather and ozone resistance. |
| PTFE | 250 | -150 | Low friction coefficient, ideal for oil seal lips. |
| TPU | 100 | -40 | Excellent mechanical properties, high tensile and tear strength. |
Suitable for various mechanical equipment to seal at specified temperatures and pressures in static or moving states. Widely used in:
Machine tools, ships, automobiles, aerospace, metallurgy, chemical engineering, mining, petroleum, and medical instruments.
Primarily used for static and reciprocating seals. When used for rotary motion, it is limited to low-speed devices. Installed in rectangular grooves to provide excellent sealing and shock absorption.
