EVA interlayer film for smart glass laminating with low processing temperature

When laminating smart glass, particularly with PDLC film (Polymer Dispersed Liquid Crystal), managing temperature is crucial. PDLC film is a heat-sensitive material that can be easily damaged if exposed to high lamination temperatures. This can result in issues like bubbles, delamination, or even failure of the lamination process. To mitigate these risks and ensure a high lamination success rate, it is essential to use an EVA interlayer film with a lower processing temperature.

The EVA interlayer film designed specifically for smart glass laminating has a significantly lower processing temperature of 110°C, compared to the traditional 130°C required for standard EVA films. This makes it an ideal solution for laminating switchable glass and other heat-sensitive applications, as it minimizes the risk of damaging the PDLC film while ensuring a strong, durable bond.

Features of eva film for glass lamination

Benefits of EVA Interlayer Film for Smart Glass:
- Lower processing temperature of 110°C reduces the risk of damage to heat-sensitive PDLC films.
- Perfect for switchable glass laminating and other applications requiring heat-sensitive materials.
- The adhesion of EVA interlayer film with PDLC film is carefully balanced. If the adhesion is too strong, the PDLC film may experience excessive tensile force from the EVA film, potentially causing damage. On the other hand, if the adhesion is too weak, it can lead to delamination issues, compromising the integrity of the laminate. Achieving the right level of adhesion is crucial to ensure both durability and performance in smart glass applications.
