Generally speaking, a isothermal container needs to have good sealing performance to ensure stable temperature and pressure, as well as reduce heat loss and the impact of external environment on the temperature inside the container. Therefore, many isothermal containers adopt advanced sealing technologies and materials, such as metal sealing rings, rubber sealing rings, silicone sealing rings, etc. These sealing materials have good high-temperature resistance, corrosion resistance, and wear resistance, which can ensure that the container maintains a good sealing effect during long-term use.
In addition, the design and manufacturing process of containers can also affect their sealing performance. Some high-quality isothermal containers will adopt a multi-layer sealing design to improve their sealing performance. Meanwhile, manufacturing processes can also affect sealing performance, such as welding and assembly processes. If the manufacturing process is poor or the sealing material is improperly selected, it may lead to a decrease in sealing performance.
