Versalis Clearflex® CL 508 Octene Copolymer Linear Medium Density Polyethylene  (discontinued **)
Categories: Polymer; Film; Thermoplastic; Polyethylene (PE); Medium Density (MDPE); Linear Medium Density Polyethylene (LMDPE), Film
Material Notes: Clearflex CL 508 is an octene copolymer linear medium density polyethylene (C8-LMDPE), with antioxidants, suitable for cast film extrusion.

Films manufactured with Clearflex CL 508 exhibit a good balance between rigidity and stretchability.

Main Applications: Clearflex CL 508 is recommended for the production of film characterized by optimum mechanical resistance and high rigidity (hygienic films). Its high Vicat softening point makes Clearflex CL 508 the ideal choice for the production of films for food which are submitted to pasteurization or sterilization processes. Moreover, Clearflex CL 508 can be used, for its slip-cling properties, as external layer in coextrusion structures.
