LNG (liquefied natural gas) storage and transportation imposes stringent requirements on cryogenic insulation materials. Due to the extremely low temperatures and complex environments, cryogenic elastic felt has become a key material in many insulation systems. LNG elastic felt typically employs an inorganic fiber composite structure design, possessing characteristics such as high flexibility, low thermal conductivity, and good dimensional stability, allowing it to adapt to the thermal expansion and contraction of equipment and pipelines under cryogenic conditions.

In LNG tanks, cryogenic pipelines, and regasification stations, the presence of elastic felt reduces heat loss, improves energy efficiency, and helps the system maintain a stable operating temperature. Due to its fiber structure's compressive strength, it is less prone to collapse or pulverization under prolonged freezing conditions, thus extending the service life of the insulation layer.

During construction, it is crucial to ensure full adhesion between the cryogenic elastic felt and the equipment surface, and to use an outer protective layer suitable for cryogenic environments for fixation and protection to minimize environmental impact. With the widespread use of LNG in the energy sector, the demand for elastic felt insulation materials will further increase.
