Spectraseal profiles are predominately used for extreme and demanding application requirements where conventional moulded elastomers or thermoplastics cannot be used due to material limitations. Application conditions such as:
  • Extreme temperatures: from cryogenics temperatures to +290°C (+550°F)
  • Low friction: friction sensitive application such as valves or pressure switches that are required to operate with a very light spring load or pressure differential
  • Presence of aggressive chemicals: most of the engineered plastic materials used, such as PTFE based compounds, have virtually universal media compatibility
  • High-pressure gas: most engineered plastic materials do not exhibit explosive decompression, which is a common problem for many elastomer-based materials
  • Abrasive or non-lubricated environment: media such as water, paints, resins and drilling mud can be very abrasive to elastomer based sealing materials
  • High surface speeds and or pressures: Due to the low friction characteristics of the materials it is possible to tolerate high surface speeds even without lubrication
