LyondellBasell Alathon® H4620 High Density Polyethylene, Injection Molding Grade
Categories:	Polymer; Thermoplastic; Polyethylene (PE); High Density (HDPE); High Density Polyethylene (HDPE), Injection Molded
Material Notes:	Alathon H4620 is a medium-flow resin that exhibits good cold temperature impact performance, enhanced processing and thermal stability. Typical applications are thinner-walled parts that require chemical resistance. Regulatory Status: H4620 meets the requirements of the Food and Drug Administration regulation 21 CFR 177.1520. This regulation allows the use of this olefin polymer in "...articles or components of articles intended for use in contact with food." Specific limitations or conditions of use may apply. Contact your Equistar sales representative for more information. Specific recommendations for processing H4620 can only be made when the processing conditions, equipment and end use application are known. This product is from the former Equistar product line.
