管材采用高密度聚乙烯(HDPE)材料制成，具有更高的耐高温性能和抗压强度。经过双交联工艺的PEXb复合管可以在95℃的温度下长期使用，使用寿命可以达到50年以上的保证，特别适合应用于高温条件的散热器采暖(70℃以上)系统的连接。

The pipe is made of high density polyethylene (HDPE) material, which has higher high temperature resistance and compressive strength. After the double cross-linking process, the PEXb composite pipe can be used for a long time at a temperature of 95 ° C, and the service life can reach more than 50 years, which is especially suitable for the connection of radiator heating (above 70 ° C) systems under high temperature conditions.
