Westlake EM184AA Low Density Polyethylene (discontinued **)
Categories:	Polymer; Thermoplastic; Polyethylene (PE); Low Density (LDPE)
Material Notes:	WESTLAKE low-density polyethylene EM184 is a low density injection-molding formulation suggested for the production of closures where a high melt index is needed to meet shrinkage requirements and fast molding cycles. It molds with unusual ease and is suggested for large, think-walled items where stress-crack resistance is not a primary requirement. WESTLAKE polyethylene EM184 can be used as a base for color concentrates. Application/Uses Food-contact applications Lids Medical FDA: This material complies with FDA regulations in 21 CFR, section 177.1520. Kosher Compliant. All information provided by Westlake Chemical
