Marble protective film performance requirements and use requirements
- Mar 01, 2019 -

Marble protective film is mainly used for surface protection of various plates (sheets), such as polished surfaces of various specifications of stainless steel and aluminum alloy, matte surface, brushed surface; oxidized and oxidized colored surface of aluminum alloy; and various metal plates Surface protection of coating surfaces such as color steel plates, colored aluminum composite panels, and electrophoretic color plates for transportation, storage, and mold processing.
In order to have better use effect, the marble protective film is required to be inert to the surface of the material to be protected; the adhesive material has good adhesion property, and the protective film does not rise and fall during material handling and processing; The marble protective film itself has good weather resistance and stability to holding the adhesive. 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.
During the use of marble protective film, it is required to be suitable for stickiness: easy to stick and easy to tear; stable peeling force: small change over time, that is, the smaller the peeling force is as small as possible; good weather resistance: in the case of sunlight exposure, the service period is long Half a year to one year; long storage period: stored in the warehouse for more than one year, no change in quality; in addition, it must meet the tensile strength, elastic modulus, elongation and so on.
