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 (see Technical Data Sheet for limitations and more information):
- ASTM D2513-18a for Polyethylene (PE) Gas Pressure Pipe, Tubing and Fitting, Category C per Table 5
- ASTM D3350 Cell Classifications: PE445574C and PE445576C. For Oxidative Resistance Classification Categorization values (CC) please contact your LyondellBasell Technical Service Engineer or Sales Manager.
