Description

HDPE B5308 is a multi-modal HMW HDPE grade specifically designed for blow molding floaters for floating photovoltaic (PV) panel systems. It has outstanding ESCR (environmental stress crack resistance), excellent mechanical properties, very good toughness and stiffness balance, long lifetime and easy blow molding processability. B5308 is also suitable for large size containers such as water tanks and transportation containers when high ESCR and toughness/stiffness balance is required.
