TPU film is a type of plastic film
TPU film is a plastic film made mainly of polyurethane (TPU), hence it is also known as TPU film. Due to its excellent wear resistance, oil resistance, waterproof, and dustproof properties, it is widely used as a protective film on electronic products such as mobile phones and tablets. However, some users may notice that the TPU membrane turns yellow after a period of use, so why is this? Let's explore below.
There may be multiple reasons for the yellowing of TPU membranes. Firstly, there may be issues with the TPU membrane material itself, and the additives added during the production process may react with the usage, causing the membrane to turn yellow. In addition, prolonged exposure to ultraviolet radiation can cause the TPU film to age and turn yellow, while also being affected by environmental humidity and cleanliness. If there is dirt on the surface, it may also cause the TPU film to turn yellow. Incorrect usage methods, such as using inappropriate cleaning agents, scrapers, or not cleaning the surface before installation, can also cause the TPU film to turn yellow.
So, how to prevent and maintain the usage environment of TPU membranes? Firstly, maintain cleanliness and dryness to avoid prolonged exposure to ultraviolet radiation. Secondly, appropriate cleaning agents and scrapers should be used during use to avoid scratching with excessively sharp tools. In addition, during installation, it is necessary to ensure that the surface is clean and tidy to avoid residues affecting the adhesive energy and color of the film. The yellowing of the membrane is mainly caused by material issues, usage environment, and improper use. Therefore, attention should be paid to maintaining a clean and dry environment during use, using appropriate tools and correct installation methods to avoid yellowing. If you find that the film has turned yellow, you can try using a professional cleaner or replacing it with a new TPU film to solve the problem.
