陶氏化学(Dow Chemical)

产品描述

Industrial Standards Compliance:
- ASTM D 3350: cell classification PE445520A (See NOTES 1)
- American Association of State Highway and Transportation Officials (AASHTO) M294/MP7 (See NOTES 2)

DOW DGDA-2485 NT High Density Polyethylene resin is produced using UNIPOL™ II process technology and meets the needs of a wide variety of end uses including profile extrusion applications such as corrugated pipe. It combines excellent ESCR/NCLS with superior toughness and processability.

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).
(2) Natural resin extruded under proper conditions with carbon black masterbatch DFNF-0092 (6.5%).
