What are the factors that are related to the viscosity of the plastic protective film?
- Feb 06, 2018 -

Performance is a measure of the quality of plastic protective film is good or bad standards, and the viscosity as one of the quality of the plastic protective film has played an important role, and what factors relate to its performance in this regard ? This is also the key to control the viscosity of plastic protective film.


Most of the plastic protective film in the industry is made of acrylic pressure-sensitive adhesive coating, so its stickiness mainly depends on the ratio of raw rubber and the amount of glue; such protective film appears in the process of application sticky high,In addition to the high viscosity of the protective film itself, but also with stickers, storage pressure and temperature are directly related.


At present, the viscosity of plastic protective film mainly depends on the thickness of the silicone. The high viscosity means that the thickness of the silicone is high. However, too high viscosity tends to overflow due to thermal expansion and contraction. Therefore, the viscosity of the protective film should not be too high High, so hard to tear off the protective film.


Different products corresponding to the plastic protective film required viscosity is different, so in the design time to go through many tests, to find the thickness of the appropriate data, combined with the thickness of the protective film to ensure the smoothness of the product, high defense Shaving, high-definition purpose.


As we all know, pressure-sensitive adhesive is only sensitive to pressure, so the pressure can be properly adjusted after the cover or affixed to control the viscosity of the pressure; if the plastic protective film itself is high viscosity, consider the weather to be cool after use, because the following 20 degrees Plastic protective film can obviously feel the relative decline in viscosity.
