合適的粘附力：不起翹，不脫落。剝?nèi)ケＷo膜時無壓敏膠粘劑殘留。
耐候性、可加工性：數(shù)月后剝離力變化不大，不殘留。
表面呈惰性：不與該表面發(fā)生反應(yīng)，不腐蝕、不污染物質(zhì)表面。
力學(xué)性能：具有足夠的拉伸強度和伸長率，部分產(chǎn)品可以用于壓成型。

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.
