STGM9450F
STGM9450F Braskem Logo
STGM9450F is a high-density polyethylene, developed for the high molecular weight film extrusion segment produced with bimodal technology. The film produced from this resin has high tenacity and excellent resistance to impact characteristics. This resin has wide molar mass distribution that makes it easier to process. The minimum biobased carbon content of this grade is 60%, determined according to ASTM D6866.

Process: Blown Film Extrusion;

Application: Bags;Geodesic film;Perforated Bags ;
