Victrex CT-200 is an alternative to PCTFE for machined seals and related components that must operate reliably at cryogenic temperatures.
Higher tensile strength coupled with lower modulus confirms more ductility across a wider range of temperatures; testing at -196°C to +150°C indicates better sealing capabilities. Lower and constant expansion ensures more dimensional stability and minimizes the shrinkage at low temperatures. Higher thermal conductivity permits a faster reaction to temperature changes allowing the seat seal to keep interference with the steel counter-surface at all time; contributing to a more consistent sealing. Lower static and dynamic helps minimize torque and wear allowing smaller actuators and saving space and weight.
The advanced polymer is a particularly effective solution for sealing components that must perform reliably in cryogenic environments such as those encountered in liquefied natural gas (LNG) facilities and transport, and in hydrogen sealing including liquid hydrogen.
