Alathon L4904

Alathon L4904 is a bimodal, high molecular weight high density polyethylene (HDPE HMW) grade. Exhibits excellent processing, high resistance to pipe failure by rapid crack propagation and slow crack growth mechanisms. Shows grease- , corrosion- and shatter resistance and high crystalinity. Designed for pressure pipe extrusion process. Recommended for pressure pipe applications including gas distribution, industrial piping, mining, oil & gas gathering, municipal water service lines and sewers. Complies with 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 and CSA B137.4 for PE piping systems for gas services.
