Westlake TRUCOAT® EC476 Extrusion Coating LDPE
Categories:	Polymer; Thermoplastic; Polyethylene (PE); Low Density (LDPE); Low Density Polyethylene (LDPE), Extrusion Grade
Material Notes:	TRUCOAT® EC476 is a low density polyethylene resin designed for extrusion coating and laminating applications where high coating speeds and good drawdown are required. It adheres well to paper, provides a good moisture barrier, and is heat-sealable at low temperatures. Where required, test specimens are compression molded according to ASTM D 1928 at 50% relative humidity and 23°C. Information provided by Westlake Chemical.
