HDPE Braskem PE SGM9450F 高分子量,高密度,可更新资源,宽分子量分布,食品
材料简述：
Description:
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 content of this grade is 96%, determined according to ASTM D6866.
Application:
Bags in general (like T-shirt bags, Handle Bags, Star Bags, others);
Geomembranes.
