Requirements for the use of PE protective film

PE protective film is often used to protect the surface of doors and windows, aluminum profiles, and glass, so what are the requirements for its use?

1. Appropriate viscosity: easy to stick and tear; (test the applicable viscosity of the product according to the product tip)

2. Stable peeling force: small changes over time; (that is, the smaller the peeling force rise, the better)

3. Good weather resistance: under the conditions of sun exposure, the service life is up to half a year;

4. Long storage period: stored in the warehouse for more than one year without any change in quality;

Five, no pollution, no corrosion: the adhesive is inert and will not chemically react with the surface of the material to be adhered;

6. Excellent mechanical properties: tensile strength, elastic modulus, elongation, etc. that meet user requirements.
