CONTINUUM™ DGDA-2488
HDPE
陶氏化学(Dow Chemical)
产品描述
CONTINUUM DGDA-2488 NT Bimodal Polyethylene Resin is produced using UNIPOL™ II process technology. It is specifically designed for use in all duct and cable in conduit (CIC) applications for both telecommunications and power cables. Typical uses include high performance conduit for fiber optic networks and 5G expansion. The natural resin combined with color concentrate can be readily processed by any current duct or conduit extrusion method in all sizes at commercial rates.
Industrial Standards Compliance:
ASTM D 3350: cell classification PE435440A
