When it comes to outdoor applications, the issue of yellowing in protective films is a major concern. Let's explore how Shenzhen Everbright Yuan Film Co., Ltd.'s PU glue PET protective films stand up to this challenge.
Understanding the Yellowing Problem
Yellowing in protective films is often caused by the breakdown of materials due to UV radiation, oxygen, and heat. These factors can react with the components of the film, especially the adhesive layer, leading to a change in color. This not only affects the aesthetic appearance but also can reduce the film's protective properties.
Everbright Yuan's Solution: High - Quality PU Glue
At Everbright Yuan, we use a special type of PU glue in our PET protective films. This glue is formulated with advanced technology to enhance its weather resistance. Our R & D team, in collaboration with experts from Harbin Institute of Technology, has developed a formula that minimizes the risk of yellowing. The PU glue has excellent UV - absorbing properties, which prevent the UV rays from penetrating and degrading the film.
Testing for Durability
Our PU glue PET protective films undergo rigorous testing to ensure their long - term performance. We subject the films to simulated outdoor conditions, including intense UV exposure, high and low temperatures, and humidity. The results are impressive. After extended periods of testing, our films show minimal signs of yellowing, maintaining their original transparency and protective capabilities.
Wide - Ranging Applications
Our weather - resistant PU glue PET protective films are suitable for a broad range of applications. In the aviation and aerospace industry, they protect sensitive components from the harsh outdoor environment. In the transportation sector, they are used to protect vehicle bodies and windows. In the medical industry, for outdoor medical equipment, these films ensure that the equipment remains in good condition, free from weather - related damage.
