MDPE (Medium-Density Polyethylene) CAS#9002-88-4
Our HDPE and LLDPE grades exhibit outstanding mechanical performance characteristics including high impact strength even at low temperatures, excellent flexural modulus for structural rigidity, superior creep resistance under sustained loading, and remarkable environmental stress crack resistance, making them eminently suitable for demanding industrial applications such as pressure pipes, corrugated conduits, heavy-duty pallets, large-volume storage tanks, and automotive fuel systems requiring long-term reliability.
