The solar film can resist ultraviolet radiation. Presumably, ultraviolet protection is a direct demand. Of course, after all, it is also one of the direct factors that many car owners will buy solar films, but don't confuse it with ultraviolet protection and heat insulation. You know, ultraviolet rays are really powerful.
If there is no solar film, the driver's hands will become red and painful, and the color will deepen. Due to the destruction of ultraviolet rays, the solar film will age and fade, and then lose its efficacy. Therefore, we must choose products with strong resistance to ultraviolet and infrared rays.
