Formula: HDPE
Form: Foil/Film/Sheet
Material: High Density Polyethylene (HDPE)
CAS Number: 9002-88-4
Commodity: Polymers
High-density polyethylene (HDPE) film is a durable and versatile material with exceptional chemical resistance and high tensile strength, making it ideal for applications in energy storage, electrochemical systems, and environmental protection. It has been used to advance radiation-grafted anion-exchange membranes (RG-AEMs), enhance fuel cell performance and enable use of sustainable, nonprecious-metal catalysts in stationary power applications. The high conductivity of HDPE also supports metal-air and redox-flow batteries, electrolysers, and salinity gradient power systems. Furthermore, HDPE’s capacity for surface modifications expands its use in biomedical and materials science research, positioning it as a crucial material for innovation in energy and healthcare sectors.
