Alathon L4904LS

LyondellBasell

Description

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.  Please contact your LyondellBasell Technical Service Engineer or Sales Manager for an approved color and black masterbatch list.  When L4904LS is combined with a LyondellBasell approved color or black masterbatch at the correct use level, this compound may meet the following standards or requirements:

  • ASTM D3350 Cell Classifications: PE445574C, PE445576C. For Oxidative Resistance Classification Categorization values (CC), please contact your LyondellBasell Technical Service Engineer or Sales Manager.
  • NSF Standard 14 and Standard 61 for Potable Water Pipe and Fittings
  • Plastics Pipe Institute (PPI) PE 4710 and PE 100 per PPI TR-3
