As a country with high energy consumption, Chinese demand for clean energy has been increasing due to the gradual improvement of the economy and the living standards of its citizens. Natural gas is one of the most widely used clean energy sources, and the country has vigorously promoted its use to alleviate environmental issues. As a result, China has invested heavily in the construction of LNG receiving terminals and plants in coastal areas. This has led to the rapid development of the LNG industry and placed high demands on the safety and efficiency of LNG-related cryogenic equipment. Due to the extremely low temperature of LNG, it is necessary to consider heat loss and heat intrusion in the design of LNG-related cryogenic equipment. In this study, high-density polyethylene was chosen as the low-temperature sealing material with the aim of controlling heat loss and reducing heat intrusion. Compression, compression rebound, and hardness tests were conducted on high-density polyethylene at temperatures of 25°C, -29°C, -50°C, -110°C, -162°C, and -180°C. The maximum stress values, compressibility, resilience, and hardness of high-density polyethylene at different temperatures were analyzed.
