CONTINUUM™ DGDA-2492 NT

About
CONTINUUM™ DGDA-2492 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 natural gas distribution pipes, large diameter industrial piping, mining, sewage, and municipal water service lines. Industrial Standards Compliance: ASTM D 3350: cell classification Natural – PE445576A CC0(MRS) Black – PE445576C CC2 (MRS) (See NOTES A) Natural – PE445574A CC0(HDB) Black – PE445574C CC2 (HDB) (See NOTES A) Plastics Pipe Institute (PPI): TR-4: Black Pipe – CONTINUUM™ DGDA-2492 BK (See NOTES A) ISO PE100 pipe grade – MRS 10 @ 20°C; CRS 6.3 @ 60°C, 11 yr ASTM PE4710 pipe grade – 1600psi HDB and 1000psi HDS @ 73°F, and 1000psi HDB @ 140°F NSF International: Standard 14 and 61 Black Pipe – DGDA-2492 Black (See NOTES B) Consult the regulations for complete details. NOTES: (A) The first five numbers of the cell classification are based on natural resin. The last number and letter are based on black resin (natural resin plus 6.5% DFNF-0092). (B) Natural resin extruded under proper conditions with carbon black masterbatch DFNF-0092 (6.5%).&&
