CONTINUUM™DGDB-2490 NT bimodal polyethylene resin was prepared by UNIPOL™II process technology. This product can be used in the field of pipeline construction. These pipelines are required to withstand water pressure strength for a long time, and have the ability to resist slow cracking and fast cracking. Applicable applications include natural gas transmission and distribution pipelines, industrial pipelines, mining, sewage and municipal water supply and drainage pipelines.

remarks:
(1) the first 5 digits in the standard grade represent the primary color resin used in the product. The last digit and the following letters represent black resin (6.5% DFNF-0092 is added to the primary color resin).
(2) Under appropriate processing conditions, carbon black masterbatch DFNF-0092 (6.5%) can be added to extrude the primary color resin.
