SGF4950
SGF4950 Braskem Logo

SGF4950 is a high-density polyethylene copolymer, developed for the blow-molding segment. It shows well balanced properties between impact and stiffness, combined with high environmental stress cracking resistance and processability. The minimum biobased carbon content of this grade is 96%, determined according to ASTM D6866.

Process: Compression Molding;Extrusion Blow Molding;

Application: Blow molding small volumes;Cosmetic packaging;Tissue and hygiene packaging;
