LyondellBasell Hyperzone HY4008 HDPE
Categories:	Polymer; Thermoplastic; Polyethylene (PE); High Density (HDPE)
Material Notes:	Hyperzone HY4008 is a bimodal, high molecular weight, high density polyethylene resin with excellent processing characteristics produced with LyondellBasell's new proprietary Hyperzone PE process technology. HY4008 is selected by customers for pressure pipe applications including gas distribution, industrial piping, mining, oil & gas gathering, municipal water lines and sewers. Customers typically use HY4008 in applications requiring an excellent balance of processability and toughness, along with high resistance to pipe failure by rapid crack propagation and slow crack growth mechanisms. When HY4008 is combined with a LyondellBasell approved color or black masterbatch at the correct use level, this compound may meet the following standards or requirements: ASTM D2513-18a for Polyethylene (PE) Gas Pressure Pipe, Tubing and Fitting, Category C per Table 5 ASTM D3350 Cell Classifications: PE445574C and PE445576C. CSA B137.1 for Pipe, Tubing and Fittings for Cold-Water Pressure Services CSA B137.4 for Polyethylene Piping Systems for Gas Services: PE4710 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) PE4710 and PE 100 per PPI TR-3 Status: Commercial Availability: Asia-Pacific; North America; South & Central America Application: Drainage Pipe; Drinking Water Pipe; Gas Pipe; Industrial; Soil & Waste Pipe Market: Industrial, Building & Construction; Pipe Processing Method: Pipe Information provided by LyondellBasell.
