SGM9450F 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 96%, determined according to ASTM D6866.

Polymer Name: High Density Polyethylene (HDPE), High Density Polyethylene (HDPE) Compound

Processing Methods: Blown Film Extrusion, Cast Film Extrusion, Extrusion, Film Extrusion
