Plastic sheet pe protective film performance requirements

- Feb 03, 2019-

1. The protective film is inert to the surface of the material being protected

2. The protective film has adhesive properties to the material to be protected, and the protective film does not rise and fall during material handling and processing;

3. The protective film has weather resistance and stability of adhesion. After several days or a long time, the peeling force is not significantly increased, and it is easy to remove. When removed, no residual glue remains on the protected surface, and no shadow is left.

4. Low crystal point 

Usage requirements

1. Suitable viscosity: easy to stick and easy to tear;

2. The peeling force is stable: the change over time is small, that is, the smaller the peeling force increases, the better;

3. Good weather resistance: under solar exposure conditions, the use period is up to six months to one year;

4. Long storage period: stored in the warehouse for more than one year, no change in quality;

5. No pollution, no corrosion: the adhesive is inert and will not chemically react with the surface of the material to be bonded;

6. Tensile strength, elastic modulus, elongation, etc. that meet user requirements
