Basic knowledge and use of PE protective film
Dec 10, 2021
PE protective film, full name Polyethylene, is the simplest polymer organic compound and the most widely used polymer material in the world today. PE protective film uses special polyethylene (PE) plastic film as the base material, and is divided into high-density polyethylene protective film, medium-density polyethylene and low-density polyethylene according to the density.
Ultra-low viscosity film retention:
Characteristics: Thick (20.03mx0. 003), wide (s1. 3), high (100-1500), base material (PE), peel strength (S5g/cm), temperature resistance (60); stretch rate (> 400)
Uses: easy to use, easy to stick and tear, no glue residue, suitable for organic plates, instruments, display screens, glass lenses, plastic lenses, etc.
Low-viscosity protective film:
Characteristics: Thick (20.03m+0.003), wide (S1.3), high (100-1000), base material (PE), peel strength (10-20g/cm), temperature resistance (60), tensile Elongation (>400)
Uses: stable adhesion, good adhesion, good peeling performance, no glue residue, suitable for steel mirror plates, titanium metal, smooth plastic plates, silk screens, nameplates, etc.
Medium and low viscosity protective film:
Characteristics: Thick (20.03m+0.003), wide (S1.3), high (100-1000), base material (PE), peel strength (30-50g/cm), temperature resistance (60), tensile Elongation (>400)
Uses: Stable adhesion, good adhesion, good peeling performance, no residual glue phenomenon, suitable for furniture Polaroid board, stainless steel board, ceramic tile, marble, artificial stone, etc. .
Medium viscosity protective film:
Features: Thick (20.05+0. 003), wide (S1. 3), high (100-800), base material (PE), peel strength (80-100g/cm), temperature resistance (60), tensile Elongation (>400)
Uses: Stable adhesion, good adhesion, good peeling performance, no residual glue phenomenon, suitable for fine-grained frosted board and surface protection of general hard-to-stick materials, etc.
High viscosity protective film:
Characteristics: Thick (20.05+0.003), wide (S1.3), high (100-800), base material (PE), peel strength (80-100g/cm), temperature resistance (60), stretch Elongation (>400)
Uses: Stable adhesion, good adhesion, good peeling performance, no glue residue, suitable for fine-grained frosted board, aluminum-plastic board, hard-to-stick plastic board, etc.
Ultra-high viscosity protective film:
Characteristics: Thick (20.04+0. 003), wide (S1. 3), high (100-800), base material (PE), peel strength (above 100g/cm), temperature resistance (60), stretch Rate (>400).
Uses: Very high viscosity, water-based acrylic is used as pressure teaching adhesive, easy to use, easy to stick and tear, and no residual limbs. Suitable for hard-to-stick materials such as rough-grained aluminum plates.
The biggest advantage of PE protective film is that the protected product is not polluted, corroded, scratched during production, transportation, storage and use, and protects the original smooth and shiny surface, thereby improving product quality and market competitiveness .
