Description

Protective film for glass material of car windows

This creation is a kind of glass protective film, especially a kind of protective film of glass material used for car windows, as the protection of car windows.

Press, the front block, rear block, side window or sunroof of the car will be covered with heat-insulating paper, through which the heat-insulating paper is used for heat insulation and UV resistance, but it has high heat insulation, high UV resistance and high light transmission properties. The price of insulation paper is quite expensive.

The traditional insulation paper is made of plastic, which has insufficient hardness (usually 2H~3H) and is not scratch resistant, so most of it can only be applied to the inner side of the car window, and its use is limited; in addition, cars will use it The suction cup holder is adsorbed on the heat insulation paper in the car window to fix the related accessories. After long-term use, the adhesion of the heat insulation paper to the car window is easily affected by the suction force, and even the heat insulation paper will be damaged.

In addition, plastic insulation paper also has problems such as easy expansion and contraction, yellowing, and moisture absorption, so the service life is usually not long.

Moreover, the surface of plastic heat-insulating paper is difficult to surface treatment, and cannot be treated with anti-fogging. Therefore, when the temperature difference between the inside and outside of the car is large, it is easy to cause fogging on the inside of the car window, which affects driving safety.
