Product Description
CONTINUUM™ DGDA-2420 NT Bimodal Polyethylene Resin is produced using UNIPOL™ II process technology. This product is formulated with a UV stabilizer for outdoor storage. 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, irrigation and drip tube.

Industrial Standards Compliance:
  • ASTM D 3350: cell classification PE234373E
  • ISO PE 80 pipe grade
  • ASTM PE 2708 pipe grade - 1250 psi HDB @ 73F, 800 psi HDS at 73F, and 1000 psi HDB at 140F
Consult the regulations for complete details.
