With the continuous development trend of the touch screen manufacturing industry, the standards for touch display screens are getting higher and higher, and the standards for materials are getting higher and higher. Whether a protective membrane can have excellent protection function is also a question that the touch display manufacturer is very concerned at this stage.
In the touch screen manufacturing industry, PET manufacturers have used the use of acrylic gel protective film and silicone protective film. However, the acrylic glue protective film and silicone protective membrane have always had many quality problems, such as residual gums, steam bubbles, fog, migration and other conditions. The PU protective film is a new optical protective film product that replaces the acrylic gel protective film and the silicone protective film. It can effectively solve the problems of residual gum, steam bubbles, fog, migration, and have very good high temperature resistance and high humidity resistance. At this stage, there are nearly 30 producers of the PU protective film (the key includes Japan, South Korea and Taiwan, and Mainland China). It has increased more than ten in 2013, and China accounts for the majority. The yuan to 40 yuan is different, and the domestic PU protective film is more than 10 yuan.
Nowadays, the technical and products of most PU protective film manufacturers are in immature links, and the unstable phenomenon of foggy, foaming, residual glue and other unstable conditions. This also makes PET manufacturers who just introduced PU protective film products are more headache and confused. As PET manufacturers who have just imported PU protective film lack the use and master of PU protective film products, lack of appropriate detection methods and discern professional capabilities, then According to the cost fee, it is generally tended to select PU protective film products with low price. Although some PU protective film products can be tested by PET manufacturers, the products have foggy, steam bubbles, steam bubbles, and foam after entering the application of PET manufacturers. Unstable conditions such as residual glue. There are only a handful of manufacturers that can ensure the long -term stable PU protective film. This article is closely discussed around the above problems.
