| Barex 218 Extrusion Grade resin is an impact modified acrylonitrile-methyl acrylate copolymer with increased flexibility and higher impact resistance than the standard Barex 210 resins. It combines excellent gas barrier properties with a wide range of chemical resistance. It can be used for producing high barrier packaging by film and sheet extrusion, thermoforming, and extrusion blow molding.&& |
