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, ultra high viscosity protective film
1. Ultra-low-viscosity protective film (ie, slight bottom adhesion):
Characteristics: Thickness (≥0.03m±0.003), width (≤1.3), height (100-1500), base material (PE), peel strength (≤5g/cm), temperature resistance (60), elongation (> 400)
Purpose: Easy to use, easy to stick and tear, no glue residue, suitable for organic plates, instruments, display screens, glass lenses, plastic lenses, etc.
2. Low viscosity protective film
Characteristics: Thickness (≥0.03m±0.003), width (≤1.3), height (100-1000), base material (PE), peel strength (10-20g/cm), temperature resistance (60), elongation ( >400)
Purpose: Stable adhesion, good adhesion, good peeling performance, no residual glue, suitable for steel mirror plates, titanium, smooth plastic plates, silk screens, nameplates, etc.
3. Medium and low viscosity protective film
Features: Thickness (≥0.03m±0.003), width (≤1.3), height (100-1000), base material (PE), peel strength (30-50g/cm), temperature resistance (60), elongation ( >400)
Uses: stable adhesion, good adhesion, good peeling performance, no residual glue, suitable for furniture Polaroid board, stainless steel board, ceramic tile, marble, artificial stone, etc.
4. Medium adhesive protective film
Characteristics: Thickness (≥0.05±0.003), width (≤1.3), height (100-1000), base material (PE), peel strength (60-80g/cm), temperature resistance (60), elongation (> 400)
Application: Stable adhesion, good adhesion, good peeling performance, no glue residue, suitable for surface protection of fine-grained matte boards and general hard-to-stick materials.
5. High viscosity protective film
Characteristics: Thickness (≥0.05±0.003), width (≤1.3), height (100-800), base material (PE), peel strength (80-100g/cm), temperature resistance (60), elongation (> 400)
Uses: Stable adhesion, good adhesion, good peeling performance, no residual glue, suitable for fine-grain frosted board, aluminum-plastic board, difficult-to-stick plastic board, etc.
6. Ultra-high viscosity protective film
Characteristics:
Thickness (≥0.04±0.003), width (≤1.3), height (100-800), base material (PE), peel strength (above 100g/cm), temperature resistance (60), elongation (>400)
Purpose: Very high viscosity, use water-based acrylic as pressure-sensitive adhesive, easy to use, easy to stick and tear, no residual glue. Suitable for hard-to-stick materials such as rough grain aluminum plates
