HDPE pipe is a pipe made of high-density polyethylene (English name "High Density Polyethylene", abbreviated as "HDPE"). HDPE pipe is a replacement product of traditional steel pipes and PVC drinking water pipes.
HDPE pipes must bear a certain pressure, usually PE resins with high molecular weight and good mechanical properties, such as HDPE resins, should be used. LDPE and LLDPE resins have low melt viscosity, good fluidity, and easy processing. Therefore, their melt index can be selected in a wide range, usually MI is between 0.3-3g/10min.
