At present, the thinnest and thickest PET film material in the world-film supplier
The thinnest thickness of PET film is 0.0006mm, which is currently the thinnest thickness that can be produced by manufacturers all over the world, and it is a necessary material for the production of ultra-thin sound film. The thickest thickness is 0.48mm, the actual thickness is between 0.46-0.48, and the tolerance is large. 0.48MM thick PET film is generally used for motor insulation. If it is used as a CPU fan gasket, only Dongguan PET film H10 can be used for it, because of the high precision, small tolerance, more stable fan operation, and low phoenix noise. pet knowledge: for you to analyze how to detect the quality of the release layer, everyone knows that the main function of the release film is the release, and the release film is composed of the PET film and the release layer (silicone oil layer). The quality of the release layer directly determines the quality of a release film, so today we will specifically talk about how to detect the quality of the release layer. 1. Tape test method: It is to use transparent tape to repeatedly paste the release layer of the release film. As the number of pasting increases, the release layer of the PET film will gradually increase the release force and change rapidly. The release layer is relatively close, and the slow-changing release layer is relatively better. Generally, after 3-5 times of pasting, the release force does not increase significantly. You can use it with confidence. 2. Destruction test method: It is to rub the release layer with your hands, and the white powdery substance appears, which is a silicon powder film. The one that does not drop powder is the silicone oil film. Korean materials are generally made of silicon powder, and the release layer is relatively short, and the product requirements are not high and can be used. Japanese materials are generally silicone oil film, and it is recommended to use silicone oil film for high product requirements.
