Alathon L4904 is a bimodal, high molecular weight, high density polyethylene resin with excellent processing characteristics. L4904 is selected by customers for the high performance requirements of demanding 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 an Equistar approved black at the correct loading, this compound meets the following standards:

Plastics Pipe Institute (PPI) PE 4710 per PPI TR-3

PE 100 per PPI TR-3

ASTM D3350 Cell Classification PE445574C and PE445576C

NSF Standard 14 and Standard 61 for Potable Water Pipe and Fittings

NSF Standard 358-1 for PE Pipe and Fittings for "Geothermal" Heat Pump Systems

CSA B137.1 for pipe, tubing, and fittings for cold-water pressure services

ASTM D2513 for PE gas pressure pipe, tubing and fittings

CSA B137.4 for PE piping systems for gas services
