How to Divide the Viscosity of PE Protective Film?

As a PE Protective Film Manufacturer, share with you.

PE Protective Film is one of the most common materials in protective films, and it is also the most widely used polymer material in the world today. Mainly used in hardware industry, photoelectric industry, plastic industry, printing industry, wire and cable industry, electronics industry, mobile phone digital industry. PE protective film is distinguished by thickness, color, viscosity, purpose, etc. Users can choose suitable materials according to the products used. Regarding the viscosity of PE protective film, many companies have different definitions. After years of industry experience, Shengbang has summarized the following classification of protective film viscosity:

PE Protective Film

According to the viscosity, it is mainly divided into: ultra-low viscosity protective film, low viscosity protective film, medium and low viscosity protective film, medium viscosity protective film, high viscosity protective film, and ultra-high viscosity protective film;

1. Ultra-low-viscosity protective film (that is, slight bottom adhesion):

Peel strength (≤5g/cm), stretch rate (>400), easy to use, easy to stick and tear, no glue residue. Suitable for organic plates, instruments, displays, glass lenses, plastic lenses, etc.

2. Low viscosity protective film

Peel strength (10-20g/cm), elongation rate (>400), stable adhesion, good adhesion, good peeling performance, no glue residue. Suitable for steel mirror plate, titanium metal, smooth plastic plate, silk screen, nameplate, etc.

3. Medium and low viscosity protective film

Peel strength (30-50g/cm), elongation (>400), stable adhesion, good adhesion, good peeling performance, no glue residue. Suitable for furniture Polaroid board, stainless steel board, ceramic tile, marble, artificial stone, etc.

4. Medium viscose protective film

Peel strength (60-80g/cm), elongation (>400), stable adhesion, good adhesion, good peeling performance, no glue residue. It is suitable for surface protection of fine grain frosted board and general hard-to-stick materials.

5. High viscosity protective film

Peel strength (80-100g/cm), stretch rate (>400), stable adhesion, good adhesion, good peeling performance, no residual glue. Suitable for fine grain frosted board, aluminum-plastic board, difficult to stick Plastic sheets, etc.

6. Ultra-high viscosity protective film

Peel strength (above 100g/cm), elongation rate (>400), extremely high viscosity, water-based acrylic is used as pressure-sensitive adhesive, easy to use, easy to stick and tear, no glue residue. Suitable for hard-to-stick rough-grained aluminum plates, etc. material.
