Sinopec HDPE pipe grade has broad or bimodal distribution of molecular weight. It has strong creep resistance and good balance of rigidity and toughness.
Application of the Product
HDPE pipe grade can be used in the production of pressure pipes,such as pressurized water pipes, fuel gas pipelines and other industrial pipes. It can also be used for making non-pressure pipessuch as double-wall corrugated pipes, hollow-wall winding pipes,silicon-core pipes, agricultural irrigation pipes and aluminum-plastics compound pipes. In addition, through reactive extrusion(silane cross-linking), it can be used for producing crosslinked polyethylene pipes (PEX) for supplying cold and hot water.
