LyondellBasell Alathon H4837 High Denisty Polyethylene
Categories:	Polymer; Thermoplastic; Polyethylene (PE); High Density (HDPE)
Material Notes:	Alathon high density polyethylene resins are produced in North America using slurry and solution technologies and include bi-modal HMW grades commonly used in pressure pipe and blown film, general purpose and thin-wall injection molding grades, and blown film grades known for their moisture barrier performance. Alathon H4837 is a high-flow "freezer" grade resin that exhibits enhanced cold temperature impact performance, enhanced processing, and thermal stability with good color and organoleptic properties. Typical applications are rigid food containers such as 4-, 5- and 6- quart ice cream containers that are produced in fast cycling multi-cavity stack molds. Information provided by LyondellBasell.
