Versalis Clearflex® H&T FHH 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 H&T FHH 508 is an octene copolymer linear medium density polyethylene (C8-LMDPE), with antioxidant, suitable for blown film extrusion. Films obtained from Clearflex H&T FHH 508 show good optical properties, high rigidity, high temperature resistance and excellent sealing properties. Main Applications: For its excellent optical properties and sealing performance, together with a very low gel content, Clearflex H&T FHH 508, is the ideal choice for the production of lamination films. Due to its softening point, Clearflex H&T FHH 508 is especially recommended for flexible packaging that have to withstand heat cycles such as cook-in films. Information provided by Polimeri Europa.
