Product Description
Alathon L4904 is a bimodal, high molecular weight, high density polyethylene resin with excellent processability characteristics that meet the high performance requirements of demanding pressure pipe applications including gas distribution, industrial piping, gas gathering, municipal water service lines and sewers. L4904 is designed specifically to provide superb resistance to pipe failure by rapid crack propagation and slow crack growth mechanisms. When L4904 is compounded with an Equistar approved black at the correct loading (see page 2) this formula meets the following standards.
  • Plastics Pipe Institute (PPI) PE 4710.
  • PE 100 per PPI TR-4.
  • ASTM D 3350 Cell Classification 445574C and 445576C.
  • Chemical Resistance per ASTM D 2513 (see page 2)
  • NSF Standard 14 and Standard 61 for Potable Water Pipe and Fittings.
  • CSA B137.1 for pipe, tubing, and fittings for cold-water pressure services
