How to correctly select raw materials for mobile phone protective film

Guidelines for Choosing Raw Materials for Mobile Phone Protective Film – Ensuring Quality and Durability With smartphones becoming an indispensable part of our lives, protecting screens from scratches and damage has become particularly important. Choosing the appropriate raw material for mobile phone protective film is a crucial step in ensuring mobile phone safety. Here are some key factors that can help you make wise choices. Common materials for mobile phone protective films in the market include PET (polyethylene terephthalate), TPU (thermoplastic polyurethane elastomer), and tempered glass. Each material has its unique characteristics and advantages and disadvantages. PET protective film: This is a lightweight and tough material with good scratch resistance and transparency. It is easy to install and suitable for basic protection in daily use. TPU protective film: This material is softer, with excellent elasticity and self-healing ability. It can better adapt to the curved contours of the phone and withstand minor impacts. Tempered glass protective film: Provides the highest level of hardness and durability, almost completely preventing screen breakage. They are usually thicker than other types of protective films, but they are also relatively expensive. When choosing a mobile phone protective film, it is necessary to consider the balance between thickness and hardness. A thick protective film may affect touch sensitivity, while a thin one may not be able to effectively resist external forces. As for hardness, generally speaking, higher hardness means better scratch resistance. However, excessively hard materials can also lead to fragility or lack of flexibility. A mobile phone protective film with high transparency and clarity should maintain a light transmittance of over 90% to ensure that the screen display effect does not decrease due to the application of the protective film. Meanwhile, clear image quality is also one of the standards for measuring the quality of protective films. Frequent use of wear resistance and fingerprint resistance characteristics can lead to wear and fingerprint marks on the surface of the protective film. Therefore, selecting materials with good wear resistance and fingerprint resistance is very important. These functions can be achieved by adding special coatings, such as hardened coatings or oil repellent coatings. Modern consumers are increasingly concerned about the environmental and safety attributes of products. Therefore, when selecting raw materials for mobile phone protective films, priority should be given to products that do not contain harmful substances, such as phthalates or other potentially harmful chemicals. Finally, it is crucial to choose a supplier with a good reputation and reliable after-sales service, based on their reputation and after-sales service. This can ensure that you purchase high-quality mobile phone protective film raw materials and have a professional support team to help solve any problems. By considering the above factors comprehensively, you can find the most suitable raw material for your phone protective film. Remember, the right choice not only extends the lifespan of your phone, but also enhances the user experience.
