What Is An HDPE Pipe

Hdpe pipe is a kind of pipe made of high-density polyethylene (English name is "High Density Polyethylene", referred to as "HDPE").
HDPE pipes are a replacement product of traditional steel pipes and polyvinyl chloride drinking water pipes.
HDPE pipes must withstand a certain amount of pressure, usually using PE resin with high molecular weight and good mechanical properties, such as HDPE resin. LDPE resin has low tensile strength, poor pressure resistance, poor rigidity, poor dimensional stability during molding and processing, and is difficult to connect, making it unsuitable as a material for water supply pressure pipes. However, due to its high hygiene indicators, LDPE, especially LLDPE resin, has become a commonly used material for producing drinking water pipes. LDPE and LLDPE resins have low melting viscosity, good flowability, and are easy to process. Therefore, the selection range for their melt index is also wide, usually with MI between 0.3-3g/10min.
