Sinopec HDPE pipe grade has a broad or bimodal distribution of molecular weight. It has strong creep resistance and a good balance of rigidity and toughness. It is very durable and has low sag when being processed. Pipes produced using this resin have good strength, rigidity, and impact resistance, and excellent properties of SCG and RCP.
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 pipes such as double-wall corrugated pipes, hollow-wall winding pipes, silicon-core pipes, agricultural irrigation pipes, and aluminum, and 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.
