Braskem IF33 LLDPE Injection Molding Polyethylene Copolymer  (discontinued **)
Categories: Polymer; Thermoplastic; Polyethylene (PE); Linear Low Density (LLDPE); Linear Low Density Polyethylene (LLDPE), Extrusion Grade; LLDPE/Octene, Extruded; LLDPE/Hexene, Molded

Material Notes: IF33 is a linear low-density polyethylene, narrow molecular weight butene-1 copolymer produced by the solution process for injection molding applications. It offers high fluidity, good flexibility, and low warpage. It contains antioxidant additives. This resin has been specifically developed for injection molding lid seals and lids for food containers, housewares, containers, and general purpose. IF33 has been developed to be used in the injection molding process under conditions comparable to linear low-density polyethylene. Recommended temperature profile: 150 to 210ºC.
