DOWLEX 2388 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 hot and cold water systems, e.g.:
Hot / cold drinking water distribution
Radiator connections
Heating / cooling applications
Mono- and multi-layer pipe
Industrial applications.
Main Characteristics:
Suitable for elevated temperatures without crosslinking
Outstanding taste and odor performance
Excellent processability.
Processing Recommendations:
DOWLEX 2388 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.
Complies with:
EU, No 10/2011
