HDPE SGM9450F

HDPE SGM9450F

HDPE SGM9450F is a high-density polyethylene (HDPE) resin developed under Braskem's "I'm green" portfolio, specifically designed for the high molecular weight film extrusion segment. Produced using advanced bimodal technology, this resin features a wide molar mass distribution that significantly facilitates processing. Films extruded from this grade exhibit high tenacity and excellent impact resistance characteristics. Additionally, it supports environmental sustainability with a minimum biobased carbon content of 96%, determined in accordance with ASTM D6866.

Key Features

• High-density polyethylene produced with bimodal technology.
• Sustainable formulation with a minimum of 96% biobased carbon content.
• Wide molar mass distribution for easier processing and extrusion stability.
• High tenacity and excellent impact resistance characteristics in final film applications.
• Outstanding mechanical performance, including exceptional tensile strength and elongation balance.
