(1)Advantages of using PE

Polyethylene, commonly abbreviated as PE, is one of the most widely used thermoplastics globally, known for its durability, flexibility, and moisture resistance. As a polymer, PE is available in various forms, such as high-density polyethylene (HDPE), low-density polyethylene (LDPE), and linear low-density polyethylene (LLDPE), each with distinct characteristics suitable for different applications. In the context of PV backplane films, PE is selected primarily for its protective qualities, chemical resistance, and affordability.

① Moisture Resistance: PE naturally repels moisture, which is crucial for protecting PV modules from humidity and environmental factors that can degrade their performance over time.
② Chemical Stability: PE is resistant to many chemicals, providing protection against exposure to pollutants and contaminants that could otherwise damage solar cells.
③ Flexibility and Durability: PE films are both flexible and tough, able to withstand physical stress while providing long-lasting protection for PV modules.
④ Cost-Effective and Recyclable: As a commonly used and cost-effective polymer, PE is affordable and recyclable, making it a suitable choice for manufacturers focused on both economic and sustainable production.
