Westlake MXSTEN® CV77525 LLDPE Plastomer
Categories:	Polymer; Film; Thermoplastic; Polyethylene (PE); Linear Low Density (LLDPE); Linear Low Density Polyethylene (LLDPE), Extrusion Grade
Material Notes:	MXSTEN® CV77525 is a linear low density polyethylene plastomer with very low levels of antioxidants. It does not contain any slip or antiblock additives. It is recommended as a core layer to increase the dart impact, puncture resistance, and tear properties for multilayer films that are post electron beam treated. Test specimens for blown film: nominal thickness 1.0 mils; blow up ratio 2.5:1, die gap 100 mils at 50% relative humidity and 23°C. Information provided by Westlake Chemical.
