Permeability of pneumatic rubber seal material

Update:2018-03-05

Pneumatic seal that can be used in cylinders and valves requires high flexibility, because air air is hard to seal than liquid. In addition, seal material is also important, especially when the temperature rises.

Pneumatic systems are often used in higher temperature than liquid seals. It may affect the choosing of rubber seal material. 

In the normal environment and the temperature of the workplace, the permeability of most rubber seals mateiral is lower. And they’re all similar, except silicone rubber seal material. However, it has clear difference when the temperature rises. 

All rubber seals have clear limits. Beyond the limit, rubber seal material becomes harder or more brittle.
