Alathon L4904LS is a bimodal, high molecular weight, high density polyethylene resin with excellent processing characteristics. L4904LS is selected by customers for pressure pipe applications including gas distribution, industrial piping, mining, oil & gas gathering, municipal water service lines and sewers. Customers typically use L4904LS in large diameter, thick wall applications requiring high resistance to pipe failure by rapid crack propagation and slow crack growth mechanisms.
