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