What is Cryogenic Insulation?
Cryogenic insulation refers to materials specifically designed to reduce heat transfer at extremely low temperatures, typically below -150°C (-238°F). This kind of insulation is crucial for the storage and transportation of liquefied gases, such as natural gas and liquid nitrogen, ensuring minimal energy loss and preserving the integrity of the materials involved.
