Versalis Clearflex® DFH 20 Film Grade LLDPE
Categories:	Polymer; Thermoplastic; Polyethylene (PE); Linear Low Density (LLDPE); Linear Low Density Polyethylene (LLDPE), Film Grade; LLDPE/Butene, Film
Material Notes:	Clearflex® DFH 20 is a Linear Low Density Polyethylene Resin butene comonomer produced by Unipol gas phase technology. Clearflex® DFH 20 exhibits a typical wide molecular weights distribution which gives an excellent process ability together with good mechanical characteristics. Application: Clearflex® DFH 20 is mainly designed for the production of micro-irrigation tubes, durable hoses and pipes, extruded profiles and for the production by injection molding of fittings. The outdoor use, requires the with anti-UV, to maintain excellent performance even after prolonged periods of exposure to sunlight. Property data reported for compression molded specimens.
