DOWLEX™ 2377
LLDPE
陶氏化学(Dow Chemical)
产品描述
DOWLEX 2377 Polyethylene Resin is an ethylene/octene-1 copolymer produced in the proprietary solution process of The Dow Chemical Company. It has a unique molecular structure with a controlled side chain distribution, which provides excellent stress crack resistance properties combined with outstanding Long Term Hydrostatic Strength.
Applications:
Pipes for Industrial Applications, e.g.:
Cooling water distribution
District heating/cooling
Desalination pipes
Mono- and multi-layer pipe
Main Characteristics:
Suitable for elevated temperatures without crosslinking
Excellent processability
Flexibility
Processing Recommendations:
DOWLEX 2377 Polyethylene Resin is easy to process on traditional PE processing equipment. Typical extrusion temperatures for processing range from 190 to 230 °C. For further information see our Extrusion Guideline.
Note:
The purchaser remains responsible for determining whether the use complies with all relevant regulations.
