The thermal conductivity of PEX tube is relatively good, which is mainly reflected in its thermal conductivity. Specifically, the thermal conductivity of PEX tubes is generally between 0.35 and 0.45 W/(m·K), which is relatively low compared to metal materials, but it is enough to meet the needs of application scenarios such as floor heating, cold and hot water supply pipes.

Thermal conductivity is the main parameter to measure the thermal conductivity of materials, which represents the heat flow through the unit area of the material under the unit temperature gradient. Because of its low thermal conductivity, PEX tubes show good thermal insulation performance in practical applications. This means that during heat conduction, PEX tubes can reduce heat loss and improve energy efficiency.

In addition, PEX tubes have the following advantages related to thermal conductivity:

• Temperature and pressure resistance: PEX tubes can work stably over a wide temperature range, with a safe operating temperature range of -70 ° C to +110 ° C, and have a high burst pressure, which provides a guarantee for their thermal conductivity applications under various temperature conditions.
• Non-toxic and tasteless: The PEX tube material is non-toxic and tasteless, will not pollute the water quality, and the inner wall is smooth and does not scale, ensuring the purity and heat transfer efficiency of the heat conducting medium.
• Creep resistance and aging resistance: PEX tubes have excellent creep resistance and aging resistance, and have a service life of more than long-term durability according to standards, which ensures the stability and reliability of thermal conductivity in long-term use.
• Easy installation: The PEX pipe is convenient to connect and easy to install, which reduces the difficulty and cost of construction, and also helps to improve the overall performance and efficiency of the thermal conductivity system.

In summary, the PEX pipe has excellent thermal conductivity performance, especially suitable for applications such as floor heating, hot and cold water supply pipes that require good thermal insulation performance and stable thermal conductivity.
