Technical Data
Product Description
CONTINUUM™ DGDA-2490 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 and rapid crack
propagation is desired. Suitable applications include natural gas distribution pipes, industrial piping, mining, sewage, and municipal water service
lines.
