What are the Viscosity Components of PE Protective Film?

PE protective film is divided into thickness, color, viscosity, use, etc. Users can choose the application materials according to the products used. Regarding the viscosity of PE protective film, many companies have different definitions. According to the actual situation of the company, the difference in viscosity is confirmed according to the following standards:

 PE Protective Film

According to 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 (ie, slight bottom adhesion):

Peeling 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. It is often called an electrostatic film on the market.

2. Low-viscosity protective film

Peel strength (10-20g/cm), elongation (>400), stable adhesion, good adhesion, excellent re-off function, no glue residue. Suitable for steel mirror plate, titanium metal, smooth plastic plate, silk screen, nameplate, etc. It is often called electrostatic film on the market.

3. Medium and low viscosity protective film

Peeling strength (30-50g/cm), elongation rate (>400), stable adhesion, good adhesion, excellent re-off function, no glue residue. Suitable for furniture Polaroid board, stainless steel board, ceramic tile, marble, artificial stone, etc.

Protective Film For Marbles And Ceramics

4. Medium adhesive protective film

Peel strength (60-80g/cm), elongation (>400), stable adhesion, good adhesion, excellent re-off function, 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), elongation rate (>400), stable adhesion, good adhesion, excellent re-off function, 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, and easy to show residual glue. Suitable for rough-grained aluminum plates, etc. Difficult to stick data.
