PET protective film experts analyze the three main points that can not be ignored to buy protective film
PET is mainly used for fibers and a small amount for films and engineering plastics. PET fiber is mainly used in the textile industry. PET films are mainly used for electrical insulating materials such as capacitors, cable insulation, printed circuit wiring substrates, and electrode slot insulation. Another area of application for PET films is film and base tape, such as film, X-ray film, audio tape, computer tape, and the like. The PET film is also made of a metallized film made of vacuum aluminum, such as a gold-silver wire or a microcapacitor film. Another use for PET is blow molding, a polyester pull bottle for packaging. Glass fiber reinforced PET is used in the electrical, electronic and automotive industries for a variety of coil bobbins, transformers, televisions, recorder parts and housings, automotive lamp holders, lampshades, incandescent lamp holders, relays, and rectifiers.
The following is a brief introduction to the three major points that can not be ignored in the purchase of PET protective film screen protector.
1. Microporosity of the adhesive to be adhered: Since the adhesion of the protective film occurs, the moisture of the adhesive on the surface of the protective film is quickly dried in the adhesive after the protective film is adhered, so that the protective film becomes A part of the adhesive, so the microporosity of the surface of the desired adhesive is very important for the selection of the protective film. If the microporous property of the device is large, the moisture absorption of the product is large, and the protective film which is rapidly condensed by the adhesive must be used. A protective film having a slower coagulation speed or a protective film containing a larger amount of an adhesive is used.
2. Protective film surface adhesive: The protective film is coated with adhesive on the bottom belt in the manufacturer. Usually it is fully dried and then finished into a roll. If the protective film is too moist, the protective film itself will stick tightly together. It is difficult to open when used, and some can not be used at all.
3, the price: the current market of PVC material mobile phone protective film is the cheapest, generally between 1 to 4 yuan, the work is relatively rough packaging is also relatively simple, but because the service life is relatively short need to be replaced frequently, generally specializes in mobile phone accessories The shop has PET mobile phone protective film is much more expensive than PVC, generally between 10 to 20 yuan. Workmanship and packaging are more beautiful, there are protective film customized for popular mobile phone models, do not need to cut back and buy it directly on the line. Some brands also send a mirror cloth.
With the continuous improvement of people's living standards, people are increasingly demanding the appearance of the product, and the screen protection film and protective film have also been developed rapidly, especially the screen protection film is widely used.
