The temperatures involved with LNG happens to be at the point where many elastomers and polymer materials lose elasticity and begin to behave as brittle materials. Some seals may also experience dimensional fluctuations related to temperature changes, further increasing the likelihood of failure. If temperature fluctuations are periodic, problems related to cyclic stress will arise. Another issue ...

The chemical name of polytetrafluoroethylene is PTFE (polytetrafluoroethylene). It has the highest chemical resistance and heat resistance, and can resist almost all aggressive substances. PTFE has low lubrication and high sliding speed. Wear resistance is usually low, and PTFE materials are prone to cold flow under pressure. JST Seals can produce PTFE fillers such as carbon fiber, graphite, bronz...
