LyondellBasell Alathon L4904LS HDPE
Categories:	Polymer; Thermoplastic; Polyethylene (PE); High Density (HDPE); High Density Polyethylene (HDPE), Pipe Grade
Material Notes:	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. When L4904LS is combined with a Lyondell Basell approved color or black masterbatch at the correct use level, this compound may meet: ASTM D3350 Cell Classifications: PE445574C, PE445576C, PE445574E. 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 Status: Commercial Availability: North America Application: Drinking Water Pipe Market: Industrial, Building & Construction; Pipe Processing Method: Pipe Information provided by LyondellBasell.
