Wear resistance of metals and PCTFE at cryogenic temperature

In cryogenic environments, PTFE (polytetrafluoroethylene) and PCTFE (polychlorotrifluoroethylene) are the most commonly used fluoropolymers. Fluoropolymers are polymers where the atoms have been modified. Concretely, by substitution, fluorine atoms have taken the place of hydrogen atoms. This process of atom substitution has improved the chemical resistance and thermal resistance of...

PPS polymers in electromechanical components

Due to their obvious properties, polymer materials called PPS or polyphenylene sulfides are frequently used in the manufacture of electromechanical components: contactors, switches, plugs, coils, relays or switches. But the applications are obviously numerous, as these materials have excellent mechanical and electrical resistance. PPS are available in many grades, but...

The advantage of PCTFE in the use of gaskets for LNG (liquefied natural gas)

In terms of cryogenic sealing, two main polymers used on the market are : PCTFE or PTFCE - polychlorotrifluoroethylene - and PTFE - polytetrafluoroethylene - and more specifically MPTFE, i.e. modified PTFE (TFM® or NXT®). These polymers are very much in demand, particularly in cryogenic sealing systems, thanks to their...
