LNG elastic felt is a type of insulation material specifically designed for cryogenic storage and transportation equipment. Its high elasticity, low thermal conductivity, and resistance to low-temperature shrinkage make it a crucial insulation material for LNG storage tanks, cryogenic pipelines, and cold energy recovery systems. To understand its performance advantages, it's essential to start with its material structure and core parameters.

First, the basic structure of LNG elastic felt utilizes a fiber-interlaced system, allowing it to maintain flexibility and prevent brittleness even at low temperatures. Traditional insulation materials easily lose their toughness in LNG conditions at -160℃, while elastic felt maintains continuity and stability in this temperature range, a crucial prerequisite for its application in cryogenic transportation equipment.

Thermal conductivity is a vital parameter for measuring insulation performance. LNG elastic felt maintains a low thermal conductivity at low temperatures, effectively reducing cold loss, decreasing LNG evaporation rate, and improving storage and transportation efficiency. Its low thermal conductivity makes it one of the core materials in double-walled storage tank insulation systems.

Another key performance parameter is density and compression resilience. The elastic felt has a moderate density, ensuring structural strength while maintaining good resilience under external forces, preventing loss of insulation function due to prolonged compression. This is particularly crucial in LNG ships and tank containers, where the material's compressive strength is essential for overall safety.

Its resistance to low-temperature shrinkage is also noteworthy. Many materials expand and contract at extremely low temperatures, affecting structural stability. However, LNG elastic felt exhibits low shrinkage within a range of -200°C, preventing cracking or hardening due to cold contraction. This property enhances the long-term reliability of pipeline systems.

Furthermore, the elastic felt possesses excellent vibration resistance. In LNG ships or long-haul transportation equipment, continuous vibration can cause insulation layers to powder or detach. The elastic felt's superior flexibility allows it to resist long-term mechanical stress, maintaining structural integrity.

In summary, the key performance parameters of LNG elastic felt are: low thermal conductivity, resistance to extremely low temperatures, strong compression resilience, and good structural stability. These characteristics make it an irreplaceable and vital material in LNG engineering.
