In terms of cryogenic sealing, two main polymers used on the market are : PCTFE - 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 properties at very low temperatures. They offer better ductility and also important load-bearing characteristics in environments where all other materials are very brittle, including metals.
In terms of the choice of sealing material for cryogenic valves, many characteristics are required, namely :
LNG - Liquefied Natural Gas - is a mixture of hydrocarbons composed mainly of methane, but with varying levels of ethane, propane, butane and other gases present in natural gas. In general, LNG has a boiling temperature between -166°C and -57°C at atmospheric pressure.
