Braskem LL4800N PEBDL Cast Film Extrusion Polyethylene Copolymer (discontinued **)
Categories:	Polymer; Film; Thermoplastic; Polyethylene (PE); Linear Low Density (LLDPE); Linear Low Density Polyethylene (LLDPE), Film Grade; LLDPE/Octene, Film
Material Notes:	LL4800N is a linear low-density polyethylene, copolymer of octene-1, produced by the solution process. It was developed for cast film extrusion. Films obtained with this product show a good processing performance balanced with excellent mechanical and optics properties. It contains processing aid and antioxidant additives. Its applications include: stretch films, liners, LDPE and HDPE blends, and packages for general use. LL4800N must be processed in extruder of plain matrix, adjusted to this polymer. The best conditions for processing result from an extrusion temperature between 220 to 270ºC.
