POE film is in a multi-driven cycle of technological breakthroughs, domestic substitution, and global expansion. In the future, it is necessary to focus on core technology R&D and supply chain independence, and address the competition from alternative materials and industry risks, in order to maintain a dominant position in the photovoltaic packaging material market.

POE has good elasticity, strength, aging resistance, weather resistance, and water-proof properties. Its traditional application areas are mainly in automotive parts. Photovoltaic-grade POE is mainly used for photovoltaic components, especially in the packaging of TOPCon, HJT, and perovskite.
