Alathon L4904LSC is a bimodal, high molecular weight, high density polyethylene resin with excellent processing characteristics. L4904LSC is selected by customers for pressure pipe applications including industrial piping, mining, oil & gas gathering, municipal water service lines and sewers. Customers typically use L4904LSC in large diameter, thick wall applications requiring high resistance to pipe failure by rapid crack propagation and slow crack growth mechanisms.When L4904LSC is combined with a LyondellBasell approved color or black masterbatch at the correct use level, this compound may meet the following standards or requirements:
