Product Description
CONTINUUM™ DGDA-2492N NT 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 water pipes at nuclear power facilities, natural gas distribution pipes, large diameter industrial piping, mining, sewage, and municipal water service lines.
