Product Description
Borstar MB7542 is a bimodal, high-density polyethylene produced by Borstar PE technology and intended for injection and compression moulding. This grade combines excellent organoleptic properties, environmental stress crack resistance and superior flow properties with good impact strength even at low temperatures. The improved processability, even at low melt temperature, allows energy savings and faster cycle time. This grade is designed for the caps and closures market and therefore contains a lubricant for an optimum opening torque of the cap.
