CONTINUUM™ DGDA-2502 BK Bimodal Polyethylene Resin is produced using UNIPOL™ II process technology. This product may be utilized for pipe applications where long-term hydrostatic strength combined with outstanding resistance to slow crack growth, rapid crack propagation, and high melt strength is desired. Suitable applications include natural gas distribution pipes, large diameter industrial piping, mining, sewage, and municipal water service lines. DGDA-2502 BK has excellent processability for the full range of pipes sizes and wall thicknesses to include heavy wall pipe.
