Environmental analysis of seal, o-ring failure; we sell o-rings, seals.

Environment Analysis

One major factor in possible o-ring or seal failure is the extreme and harsh environment in which o-rings and seals are expected to perform. In the semiconductor industry, the sealing environment can consist of virtually anything from inert gases at room temperatures to aggressive chemicals at very high temperatures. The sealing environment may result in chemical degradation or swelling of the sealing components. Elevated temperatures may cause seal degradation, swelling or outgassing. And the pressure - or more often, the vacuum environments - can cause outgassing and weight loss.

Contributing factors to seal failure in the sealing environment include:

Chemical -
the type of chemical(s) in service
Thermal -
the operating ranges of the seal (also any thermal cycling)
Pressure/Vacuum -
the range of pressures or vacuum levels in the process
