材料的主要特性

合适的粘附力：不起翘，不脱落。剥去保护膜时无压敏胶粘剂残留。
耐候性、可加工性：数月后剥离力变化不大，不残留。
表面呈惰性：不与该表面发生反应，不腐蚀、不污染物质表面。
力学性能：具有足够的拉伸强度和伸长率，部分产品可以用于压成型。

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.
