The protective film is one of the most common materials in the protective film, and it is also the most widely used polymer material in the world today. It is mainly used in the hardware industry, the photoelectric industry, the plastic industry, the printing industry, the wire and cable industry, the electronic industry, and the mobile digital industry. The protective film is divided into thickness, color, viscosity, and use. Users can choose the applicable material according to the products used. Regarding protective membrane viscosity, many companies have different definitions. After years of industry experience, the following division of the following protective membrane viscosity has been summarized:
According to the adhesion, the main: ultra -low viscosity protection film, low sticky protection film, low -mucosa protective film, medium sticky protection film, high sticky protection film, ultra -high sticky protection film;
1. Ultra -low sticky protection film (that is, micro -bottom sticky):
Dipping intensity (≤5g/cm), stretching rate (> 400), easy to use, easy to tear and tear, without residual gel phenomenon. Suitable for organic plates, instruments, display, glass lenses, plastic lenses, etc.
2. Low sticky protection film
Dipping intensity (10-20g/cm), stretching rate (> 400), stable viscosity, good adhesion, good peeling performance, no residual glue phenomenon. Suitable for steel mirror plates, titanium metals, light plastic plastic plates, silk prints, name names, etc.
3. Low -medium sticky protective film
Dipping strength (30-50g/cm), stretching rate (> 400), stable viscosity, good adhesion, good peeling performance, no residual glue phenomenon. Suitable for furniture Police, stainless steel plates, tiles, cloud stones, artificial stone, etc.
4. Middle sticky protection film
Dipping intensity (60-80g/cm), stretching rate (> 400), stable viscosity, good adhesion, good peeling performance, no residual glue phenomenon. Suitable for fine -grained scrubbal and surface protection of general difficulty sticky materials.
5. High -stick protective film
Dipping intensity (80-100g/cm), stretching rate (> 400), stable viscosity, good adhesion, good peeling performance, no residual glue phenomenon. It is suitable for fine-grained scrubbars, aluminum-plastic plates, difficult to stick Plastic boards, etc.
6. Ultra -high sticky protection film
Dipping intensity (above 100g/cm), stretching rate (> 400), high viscosity, water -based acrylic acid as pressure -sensitive glue, easy to use, easy to tear and tear, no residual gel Material.
