Material Notes:

Borstar MB7541 is a bimodal, natural, high density polyethylene produced by the Borstar PE technology. Borstar MB7541 combines excellent organoleptic properties, Environmental Stress Crack Resistance (ESCR) and superior flow properties as well as good impact strength and toughness even at low temperatures. The grade is designated for the caps and closure market and contains lubricants for optimum opening torque of the cap. Excellent processability, also at low melt temperature, allows energy savings and faster cycle time. Borstar MB7541 is designed for injection and compression molding.Borstar ME7542 is recommended for products requiring good environmental stress crack resistance and/or organoleptic properties and impact strength. Typical applications are caps and closures for beverages, food and industrial packaging.Information provided by the Manufacturer.
