Proper adhesive force: no upwarp, no detaching, no residual pressure sensitive adhesive when peeling the protective film.
Weather resistance, machinability: the peeling force changes slightly after months, with no residuals.
It appears inertial on the surface: no reaction with this surface, there will be no corrosion or pollution on the material surface.
Mechanical property: it is provided with sufficient tensile strength and elongation, some products can be used for molding.
