Alathon L4904

LyondellBasell

Description

Alathon L4904 is a bimodal, high molecular weight, high density polyethylene resin with excellent processing characteristics. L4904 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 L4904 in applications requiring high resistance to pipe failure by rapid crack propagation and slow crack growth mechanisms. When L4904 is combined with a LyondellBasell approved color or black masterbatch at the correct use level, this compound may meet the following standards or requirements (see Technical Data Sheet for limitations and more information):

  • ASTM D2513-09a for Polyethylene (PE) Gas Pressure Pipe, Tubing and Fittings
  • ASTM D3350 Cell Classifications: PE445574C CC3, PE445574E CC0, PE445576C CC3, and PE445576E CC0
  • CSA B137.1 for Pipe, Tubing, and Fittings for Cold-Water Pressure Services
  • CSA B137.4 for Polyethylene Piping Systems for Gas Services: PE 4710 PLUS & PE 100
  • NSF Standard 14 and Standard 61 for Potable Water Pipe and Fittings
  • NSF Standard 14 for Gas Distribution Applications
  • NSF Standard 358-1 for PE Pipe and Fittings for "Geothermal" Heat Pump Systems
  • Plastics Pipe Institute (PPI) PE 4710 and PE100 per PPI TR-3
