1. Anti-wear layer: composed of wear-resistant polyurethane, with a hardness of up to 4H;

2. Colored PET safety base layer: It is made of high-strength, high-transparent PET polyester and pigment by melt extrusion and biaxial stretching. Because the pigment is sandwiched in the PET film, it can prevent oxidation and discoloration, and the life span is as long as 8 years;

3. Metal heat insulation layer: on the PET film by vacuum evaporation or vacuum magnetron sputtering metal aluminum, silver, nickel and other nano-level metal layers with high reflectivity to infrared;

4. Composite adhesive: composed of polyurethane adhesive with good weather resistance and high transparency;

5. UV absorption layer: It is composed of special UV absorbers, which can block 99% of ultraviolet rays;

6. Transparent PET safety base layer: It is composed of high-strength, high-transparent PET polyester film, the purpose is to sandwich the metal layer in the middle to prevent metal oxidation and extend the life of the metal film;

7. Installation adhesive: It is composed of acrylate adhesive with good weather resistance and high transparency;

8. Highly transparent PET release film.
