Victrex has designed a new polyether ether ketone (PEEK) polymer for sealing applications in the cryogenics industry. The company’s Victrex CT 200 is suitable for dynamic sealing applications where gases such as LNGare stored and transported at cryogenic temperatures.
The company says that the 200 grade series exhibits improved sealing over a wider range of temperatures, compared to commonly used materials such as PCTFE. It does so at low temperatures because of its greater ductility, and at high temperatures due to its improved creep resistance.
‘We designed the new polymer with a lower coefficient of friction compared to its cousin Victrex CT 100,’ said James Simmonite, energy director at Victrex.
