Hdpe tube

Hdpe tube is a kind of pipe made of High Density Polyethylene (English name is "High Density Polyethylene", referred to as "HDPE").  

HDPE pipe is the replacement of traditional steel pipe and PVC drinking water pipe.  

HDPE tube must withstand a certain pressure, usually choose large molecular weight, mechanical properties of better PE resin, such as HDPE resin.  LDPE resin has low tensile strength, poor pressure resistance, poor rigidity, poor dimensional stability during molding, and difficult connection, so it is not suitable as a material for water supply pressure pipe.  But because of its high health index, LDPE especially LLDPE resin has become the production of drinking water pipe commonly used materials.  LDPE, LLDPE resin melt viscosity is small, good fluidity, easy to process, so the selection range of its melt index is wider, usually MI between 0.3-3G /10min.
