DOWLEX™ 2355 POLYETHYLENE RESIN

About
DOWLEX 2355 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 2355 Polyethylene Resin range from 190 to 230° C. The use of a reverse temperature profile may be beneficial on certain types of processing equipment. For further information, see our Extrusion Guideline. Applications: Pipes for hot and cold water systems, e.g.: floor heating wall heating/cooling ceiling cooling radiator connections warm / cold drinking water distribution heat recovery systems solar panels Complies with: EU, No 10/2011 U.S. FDA 21 CFR 175.105(c)(5) U.S. FDA 21 CFR 177.1520(c)3.2a (with Restrictions) Consult the regulations for complete details.&&
