The 75 μm black PET anti-static film is commonly used in various application scenarios, including:
Electronics Manufacturing: The 75 μm black PET anti-static film finds significant use in the electronics manufacturing industry. It is employed as a protective layer for electronic components, circuit boards, or sensitive devices during assembly, testing, or transportation. The black color of the film offers light-blocking properties, preventing the interference of ambient light with sensitive electronic components.
Cleanroom Environments: The 75 μm black PET anti-static film is utilized in cleanroom environments where static control is crucial. It acts as a barrier to prevent static charges from interfering with sensitive manufacturing processes or contaminating cleanroom surfaces. The film's anti-static properties, coupled with its opaque black color, help to maintain a controlled and clean environment.
Automotive Components: The 75 μm black PET anti-static film is commonly used in the automotive industry for various applications. It can be employed as a protective layer for automotive components, such as interior trims, panels, or electronic modules. The black color of the film provides an aesthetically pleasing appearance and can help to reduce glare or reflections on the components.
Light-Sensitive Materials: The 75 μm black PET anti-static film is suitable for applications involving light-sensitive materials. It can be used as a light-blocking layer for photographic films, optical equipment, or sensitive materials that require protection from ambient light. The film's anti-static properties contribute to maintaining the integrity and performance of light-sensitive materials.
Security and Confidentiality: The 75 μm black PET anti-static film is utilized in applications that require security and confidentiality. It can be employed as a privacy film for electronic displays, computer screens, or confidential documents. The opaque black color of the film restricts viewing angles, preventing unauthorized individuals from accessing sensitive information.
It's important to note that the specific suitability of the 75 μm black PET anti-static film for a particular application should be verified based on industry requirements, manufacturer guidelines, and customization options available.
The main feature of PET anti-static coated film is its ability to prevent the buildup of static electricity. It has a conductive coating on one or both sides of the film, which allows charges to dissipate and prevents static buildup. This results in improved handling, processing, and protection of sensitive components and products. The main colors of the film commonly used in application scenarios are transparent or translucent (colorless).
However, other colors such as pink, blue, and yellow may also be used, depending on the application. The color is mainly used for identification purposes to differentiate between different types of films and facilitate quality control.
To coat an antistatic fluid onto an already produced PET film, the PET film is first unwound from its original roll and passed through
a coating applicator that applies the antistatic fluid to the film's surface. This can be done using various coating methods such as
gravure, reverse gravure, Mayer rod or air knife, depending on the viscosity of the antistatic fluid and the desired coating thickness.
After the coating process, the PET film is then passed through a drying oven to remove the solvent from the antistatic fluid.
Once the solvent is evaporated, the film is rewound onto a new roll.
It is important to note that the effectiveness of this coating process depends on the type of antistatic fluid used and its compatibility
with the PET film. The process should also be carefully controlled to maintain a consistent coating thickness and avoid any defects or
inconsistencies in the final product.
