In order to reduce the pain caused by prolonged exposure to the sun, it is basically the work of car owners to attach heat insulation films to automotive glass.
According to the quality of the solar film, there will be different lengths of life. There are two manifestations of life expectancy: 1, severe fading 2, blister bags.
Remind everyone: if the solar film is bubbling, please tear it off immediately! Replace the new film!
Because the bubbling solar film releases a lot of formaldehyde. If we do not tear the bubble film, it will seriously damage our health and even cause cancer.
The car's pads, pads, paint and paint all contain formaldehyde, and the amount of formaldehyde in the car may rise after exposure to the sun. Formaldehyde is in the form of glue and stickiness. With the increase of temperature and time, the amount of volatilization will increase, which will lead to the increase of formaldehyde concentration in the car.
Formaldehyde in the car comes mainly from adhesives and plastics. After the foaming of the solar film, the closed environment between the solar film and the glass is destroyed, and the toxic gas can be released in the vehicle. Excessive formaldehyde in the vehicle can cause irritation to human respiratory tract and skin and mucous membrane, and endanger human health. Even more, it can cause leukemia and cancer. Therefore, if the solar film is bubbling, please tear it off immediately. Replace the new film!
