INTREPID™ 2498 NT Bimodal Polyethylene Resin is produced using UNIPOL™ II process technology. This product is intended for use in industrial piping system where extreme conditions such as high pressures, elevated temperatures and aggressive chemicals or hydrocarbons exist. Suitable uses include oil & gas field pipelines, gas distribution pipelines, and other industrial applications. Industrial Standards Compliance: ASTM D 3350: cell classification
NOTES: (1) 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 BK). |
