V. Differences Between Automotive Battery Insulation UV Films and Traditional Battery Insulation Films

Compared to traditional battery insulation methods such as spray coatings and blue film tapes, automotive battery insulation UV films have several significant differences:

1. Curing Method

UV Films: Utilize UV curing technology, where specific wavelengths (200-400nm) of UV light are used to cure the material quickly. This method allows for rapid and efficient curing, with stable material performance post-curing.

Traditional Methods: Spray coatings typically use thermal or chemical curing, requiring longer times and higher temperatures; blue film tapes rely on their own adhesive properties for application.

2. Performance Advantages

UV Films: Offer higher shear strength and high-temperature resistance. UV-cured insulation compounds can maintain stable performance in high-temperature environments, with shear strength exceeding 10.0MPa, making them suitable for harsher conditions.

Traditional Methods: For example, acrylic blue film tapes experience significant shear strength reduction in high-temperature environments, compromising battery safety.

3. Uniformity and Coverage

UV Films: UV curing ensures coating uniformity, avoiding issues like uneven thickness and incomplete edge coverage common in traditional spray methods.

Traditional Methods: Spray coatings struggle to achieve uniform thickness, with edges often inadequately covered; blue film tapes may have gaps during wrapping.

4. Production Efficiency

UV Films: UV curing is rapid, significantly improving production efficiency and meeting the demands of modern high-speed production lines.

Traditional Methods: Spray coatings require longer curing times, affecting production efficiency; blue film tape wrapping is relatively cumbersome and time-consuming.

5. Environmental Friendliness

UV Films: UV curing produces almost no volatile organic compounds (VOCs), making it environmentally friendly.

Traditional Methods: Spray coatings may release VOCs during curing, causing environmental pollution.

6. Cost and Economic Efficiency

UV Films: Although initial equipment investment is high, as technology matures and production scales up, unit costs are expected to decrease, offering long-term economic benefits.

Traditional Methods: Blue film tapes and powder coatings have lower material costs, but considering efficiency and performance, UV films may be more competitive.

In summary, automotive battery insulation UV films offer significant advantages in performance, production efficiency, uniformity, and environmental friendliness compared to traditional battery insulation methods. Despite higher initial costs, their superior performance and long-term benefits make them highly promising in the field of new energy vehicle battery insulation.
