Study 3 Performance of Polymeric Seals

Polymeric seals are used for many electrical applications including oil retention, nitrogen or sulfur hexafluoride gas pressure barrier, moisture exclusion, and lubricant retention. Mechanical seals and O-rings are typically specified based on polymer type (i.e., silicone, buna, Viton) and durometiy. The latter is a measure of the elastic resilience of a seal. The base polymer is chosen on the basis of compatibility with the selected contact material. Catalogs from seal suppliers are [Pg.333]

This appendix includes the chromatograms from which the mass spectral data was obtained. [Pg.335]

For some compounds, such as the aroclors, the pattern recognition of the chromatogram can be much more informative than the mass spectral information. [Pg.335]

As much as possible, each chromatogram was ran under the same conditions to allow comparison between the different compounds. [Pg.335]
