Black pet ultra-thin double-sided tape is a very important one among many electronic accessories, and its application is also very wide. It is made by double-sided coating glue on the base film tape in the form of coating. The specific structure of the black pet ultra-thin double-sided adhesive is: the top and bottom two layers are PET release films, the upper and lower layers in the middle are acrylic adhesives (that is, glue), and the middle is a black PET substrate.
After we figure out the structure of the black pet ultra-thin double-sided adhesive, let's talk about its main applications.
The main applications of black pet ultra-thin double-sided tape include the following: fixed sheet around LCD and original fixed backlight module, fixing of FPC in LEC, shading and fixing of mobile phone lens, composite graphite heat sink, composite wireless charging magnetic materials and other electronic accessories Fixed package use of functional devices.
1. For example, as shown in the figure, the black pet ultra-thin double-sided tape is mainly used for shading and shielding and fixing of windows in the application of backlight and electronic digital windows. It has superior performance, reliable structural parts and good temperature resistance.
2. Another example is the application of black pet ultra-thin double-sided tape in the field of graphite heat dissipation, which is mainly used for edge protection of graphite sheets and fixed use of graphite sheet die-cutting structural parts.
