DESCRIPTION
Borstar®FB1350 is produced using the proprietary Borstar® bimodal technology resulting in easy extrusion with superior mechanical properties. Film made from the product exhibits high dart impact strength combined with excellent yield, tensile strength, stiffness and bubble stability resulting in improved output on blown extrusion machines. Toughness is retained at low temperature. The film has high seal strength and superior ESCR properties.
