1. Application Areas:

FPU Foam is primarily used as an insulation material in NEV battery packs. It is commonly employed in battery module insulation, battery tray insulation, and separator insulation. FPU Foam's flexibility allows it to conform to various shapes and sizes, making it suitable for different components within the battery system.

RPU Foam, as a rigid polyurethane foam, is primarily used in NEV battery tray applications. Its rigid structure provides structural support and stability to the battery tray, ensuring the secure positioning and protection of the battery modules.

2. Performance and Effectiveness:

FPU Foam offers outstanding insulation performance for NEV batteries. Its closed-cell structure minimizes heat transfer, providing efficient thermal insulation. By maintaining stable operating temperatures, FPU Foam enhances battery performance, extends battery life, and protects against thermal-related issues. Additionally, FPU Foam possesses excellent cushioning and impact absorption properties, safeguarding the battery modules from external shocks and vibrations.


RPU Foam is designed to withstand mechanical stress, impacts, and environmental factors, ensuring long-lasting performance in demanding conditions. Its robust construction helps maintain the structural integrity of the battery tray over an extended period, reducing the need for frequent replacements.


3. Advantages:


- Thermal insulation: FPU Foam effectively reduces heat transfer, ensuring optimal temperature regulation and preventing energy loss in NEV batteries.

- Lightweight: FPU Foam has a low density and is lightweight, contributing to overall weight reduction in NEVs. This enhances energy efficiency and extends battery range.

- Flexibility: FPU Foam can be easily molded and shaped to fit different battery pack designs, allowing for efficient space utilization and customization.

- Impact absorption: FPU Foam's cushioning properties protect the battery modules from external impacts, ensuring the integrity and safety of the battery system.

- Durability:It is designed to withstand environmental factors, everyday wear and tear, and chemical exposure, ensuring long-lasting performance in demanding conditions. This longevity translates into cost savings as it reduces the need for frequent replacements, thereby lowering maintenance and replacement costs for NEV batteries.


RPU Foam offers similar advantages and functionalities as FPU Foam, Durability,including thermal insulation, lightweight design, impact resistance, and mechanical support. Its rigid nature allows for greater load-bearing capacity and stability in battery tray applications.

4. Functionality:


- Thermal insulation: FPU Foam minimizes heat transfer, preventing thermal fluctuations and maintaining optimal battery operating temperatures.

- Vibration damping: FPU Foam absorbs vibrations and shocks, minimizing the risk of damage to battery modules caused by external forces.

- Mechanical support: FPU Foam provides structural support to the battery system, ensuring the integrity and stability of the battery pack.

- Energy efficiency: By reducing heat transfer and energy loss, FPU Foam enhances the overall efficiency and performance of NEV batteries.


RPU Foam's rigid structure provides stability and prevents the battery modules from shifting or moving within the tray. This stability helps minimize the risk of damage to the modules due to vibrations or impacts during vehicle operation. By securely holding the battery modules in place, RPU Foam contributes to their longevity by reducing the likelihood of mechanical stress or physical damage.

In conclusion, FPU Foam and RPU Foam play crucial roles in NEV battery applications. While FPU Foam excels in insulation and cushioning applications within the battery pack, RPU Foam provides structural support and stability in battery tray applications. Together, these polyurethane foams contribute to improved performance, safety, and efficiency in the rapidly evolving field of new energy vehicles.
