For gas PE pipe The material (PE gas pipe for short) is traditional steel pipe, polychloride ethylene Replacement products of gas. The gas pipe must withstand certain pressure, usually with large molecular weight and mechanical properties http://www.zbpeg.com Good PE resin, such as HDPE Resin. LDPE The resin has low tensile strength, poor pressure resistance, poor rigidity, poor dimensional stability during molding, and difficult connection, so it is not suitable for water supply pressure pipe. However, due to its high health indicators, LDPE, especially LLDPE resin has become http://www.sdpegj.com Common materials of gas pipe. LDPE and LLDPE resins have low melt viscosity, good fluidity and easy processing, so the selection range of their melt index is wide, usually MI is 0.3-3g/10min.
