Borealis BC918CF Polypropylene Copolymer
Categories: Polymer; Thermoplastic; Polypropylene (PP); Polypropylene Copolymer

Material Notes: BC918CF is a high crystalline heterophasic copolymer film resin, based on special Borstar® nucleating technology. Optical properties will not be deteriorated as with conventional homo or copolymers at these temperatures. This grade is especially developed for the manufacturing of unoriented film for various film processing technologies like cast film process, conventional blown film process with air cooling and roll stack process for thermoformable films/sheets. Applications: BC918CF is designed for label film, lamination films, food packaging, stand up pouch film, inner layer in coextrusion, map trays, and vegetable trays.
