HDPE resins for twin-wall corrugated pipe
HDPE resins for twin-wall corrugated pipe,
HDPE QHE16A, HDPE QHE16B,
HDPE pipe grade has broad or bimodal distribution of molecular weight. It has strong creep resistance and 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 property of SCG and RCP.
The resin should be stored in a drafty, dry warehouse and away from fire and direct sunlight. It should not be piled up in the open air. During transportation, the material should not be exposed to strong sunlight or rain and should not be transported together with sand, soil, scrap metal, coal or glass. Transportation together with
toxic, corrosive and flammable substance is strictly prohibited.
Application
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 aluminumplastics 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.
Parameters
high density polyethylene (HDPE) speciality resins for twin-wall corrugated pipe with large diameter. The results indicate that the speciality resins, denoted as QHE16A/B respectively, have bending modulus over 1150 MPa, melt strength over 1.60 MPa and oxidation-induction time about 100 min. Both grades of the resins possess good processability and satisfy the requirements for producing twin-wall corrugated pipe in domestic enterprises.
