Why are high-end products using electrostatic membrane stick surface?

Electrostatic membrane, common in the industrial process of surface protective film, due to its good paste, stick take good effect, no residue, and many other advantages, is widely used in mobile phones, notebook computers, TV screen surface, the LCD screen and other high-end manufacturing field, applied in these products can effectively protect the product itself, such as new products always. Electrostatic film why so applicable to high-end products? Listen to tender young small make up stretch for you: static PE film is the most simple structure of the macromolecular organic compounds, the world's most widely used polymer materials. PE protective film with special polyethylene ( PE) Based on the material of plastic film, divided into high density PE protective film, according to the density of medium density polyethylene and low density polyethylene. PE protective film, then, is how to achieve the function of the electrostatic adsorption? Basically has the following two reasons: 1, it is in the process of the membrane corona treatment, electrostatic, increase the membrane surface area and bring to meet at the back of the glue, is beneficial to the combination of glue and membrane. 2, without the glue layer of electrostatic PE film is film for EVA material, it itself has adsorption function, a multi-layer blown film machine stretch film machine can make this product. At present, the electrostatic film about three kinds: have water-based and oil-based pressure-sensitive adhesive glue, there are no glue electrostatic film! According to production process points: one is the machine model has come out, is a kind of co-extrusion blown film machine production, the other is a co-extrusion flow machine production, their electrostatic recipe ingredients are different, the quality of the product and the price is different also, price of flat low grade of electrostatic film can make the transfer in the product surface electrostatic ingredients, causing poor products and scrap.
