According to the adhesive force, the main components are ultra-low viscosity protective film, low viscosity protective film, medium low viscosity protective film, medium viscosity protective film, high viscosity protective film, and super high viscosity protective film.

1. Ultra low viscosity protection film (that is, micro bottom sticky):

Characteristics: thick (more than 0. 03m + 0. 003), wide (less than 1. 3), high (100-1500), base material (PE), peel strength (less than 5g/cm), temperature resistance (60), tensile rate (>400).

Usage: easy to use, easy to stick, easy to tear, no residual glue, suitable for organic board, instrument, display, glass lens, plastic lens and so on.

2. Low viscosity protective film

Characteristics: thick (more than 0. 03m + 0. 003), wide (less than 1. 3), high (100-1000), base material (PE), peel strength (10-20g/cm), temperature resistance (60), tensile rate (>400).

Use: good adhesion, good adhesion, good peeling performance and no residual glue. It is suitable for steel mirror plate, titanium metal, glossy plastic plate, silk screen, famous brand name and so on.

3. Medium and low viscosity protective film

Characteristics: thick (more than 0. 03m + 0. 003), wide (less than 1. 3), high (100-1000), base material (PE), peel strength (30-50g/cm), temperature resistance (60), tensile rate (>400).

Use: good adhesion, good adhesion, good peeling performance and no residual glue. It is suitable for furniture treasure board, stainless steel plate, tile, marble, artificial stone and so on.

4. Medium stick protection film

Characteristics: thick (more than 0. 05 + 0. 003), wide (less than 1. 3), high (100-1000), base material (PE), peel strength (60-80g/cm), temperature resistance (60), tensile rate (>400).

Purpose: good adhesion, good adhesion, good peeling performance and no residual glue. It is suitable for surface protection of fine grained sand and general refractory materials.

5. High viscosity protective film

Characteristics: thick (more than 0. 05 + 0. 003), wide (less than 1.  3), high (100-800), base material (PE), peel strength (80-100g/cm), temperature resistance (60), tensile rate (>400).

Purpose: adhesion stability, good adhesion, good performance of peeling, no residual glue, suitable for fine grain grit, aluminum plastic plate, sticky plastic sheet and so on.

6. Super high viscosity protective film

Characteristics: thick (more than 0. 04 + 0. 003), wide (less than 1.  3), high (100-800), substrate (PE), peel strength (above 100g/cm), temperature resistance (60), tensile rate (>400).

Purpose: high viscosity, water soluble acrylic acid as pressure sensitive adhesive, easy to use, easy to stick, easy to tear, no residual glue phenomenon. It is suitable for hard sticky materials such as coarse grain aluminum plate.
