Compliance with industry standards
CONTINUUM™DGDB-2490 BK 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 crack generation and rapid crack growth. Applicable applications include natural gas transmission and distribution pipelines, industrial pipelines, mining, sewage and municipal water supply and drainage pipelines. remarks: (1) under appropriate processing conditions, carbon black masterbatch DFNF-0092 (6.5%) can be added to extrude the primary color resin. |
