Hdpe Tube Introduction

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. PE resins with high molecular weight and good mechanical properties are usually used, such as HDPE resins. LDPE resin has low tensile strength, differential pressure resistance, poor rigidity, poor dimensional stability during molding and difficult connection, and is not suitable as a material for water supply pressure pipes. However, due to its high hygienic index, LDPE, especially LLDPE resin, has become a common material for the production of drinking water pipes. LDPE and LLDPE resins have low melt viscosity, good fluidity, and easy processing, so their melt index can be selected in a wide range, usually MI is between 0.3-3g/10min.
