Dow Dowlex™ 2344 Ethylene-octene Copolymer
Categories: Polymer; Thermoplastic; Polyethylene (PE)

Material Notes: Product Description: Dowlex™ 2344 Polyethylene Resin is an ethylene-octene 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 very good Long Term Hydrostatic Strength. Processability: Typical extrusion temperatures for processing of Dowlex 2344 Polyethylene Resin range from 190 to230°C. The use of a reverse temperature profile may be beneficial on certain types of processing equipment. For further information, see our Extrusion Guideline.
