Thermal shock resistance represents a critical performance requirement for LNG valve seals experiencing rapid temperature transitions during initial cooldown, emergency shutdowns, and operational upsets. Cooldown from ambient to -320°F creates severe thermal gradients inducing material stress, dimensional changes, and potential cracking in temperature-sensitive materials.
