The high-quality insulation film has an anti-corrosion metal oxide layer, which can effectively block solar heat and dazzling glare, and protect the interior parts and skin of the car from harmful ultraviolet rays. The unique explosion-proof technology can prevent the window glass caused by external impact. Splash, therefore also known as heat insulation and explosion-proof film, is now the first choice for car owners to stick films. When the car owner chooses the insulation film, the following 4 important indicators can be used as the basis for distinguishing the quality of the film.
Insulation rate:Car filmBy reflecting visible light and absorbing the heat energy of infrared rays, it can achieve the effect of blocking heat. Generally, the heat insulation rate of high-quality heat insulation film is between 40% and 70%.
UV blocking rate: The UV blocking rate of general thermal insulation and explosion-proof film is only 40%, and high-quality thermal insulation and explosion-proof film is filled with ultraviolet absorbers in its deep layer, this index is not less than 98%, and the maximum can reach 99%.
Visible light transmittance: The visible light transmittance of thermal insulation and explosion-proof films on the market is between 5% and 75%. Too low light transmittance will hinder driving vision, especially the light transmittance of the front windshield must reach the traffic safety of the Ministry of Public Security. 70% of the legal requirements, otherwise it will seriously affect driving safety.
Visible light reflectivity:carWhile reflecting visible light, the film can also reflect part of the heat and maintain the privacy of the car. However, excessively high visible light reflectance will produce light pollution, so the law stipulates that the visible light reflectance of automobile films shall not exceed 10%.

Misunderstanding 1: The front windshield chooses products with endothermics
In fact, there are regulations in my country that require the light transmittance of the front windshield film to reach more than 70%. Compared with the requirements for heat insulation and UV protection of the vehicle side window explosion-proof film, clarity and safety are more basic requirements for the front windshield film. Some front windshield films are mixed with colored particles or heat-absorbing materials, which is like a foreign body mixed in the eyes of human beings, which affects driving safety. Therefore, when choosing a front windshield film, do not choose products with heat absorption agents.
Misunderstanding 2: Deep color and good heat insulation effect
Many car owners instinctively believe that the darker the car film, the better the insulation effect. This is not the case. Some inferior black tea papers simply cannot serve the purpose of blocking heat.
When the sun shines on the car film, the heat energy can be divided into three parts: penetration, absorption, and reflection. The absorbed heat energy may radiate inward or radiate out. Therefore, the heat insulation rate of the car film is the sum of the heat radiated by the car film after reflection and absorption.
Misunderstanding 3: Light colors mean high definition
Whether the car film is clear or not is determined by the material and manufacturing process of the film. Although some films are colorless and transparent, they always seem to have water in them. After watching for a long time, there will be a feeling of dazzling, but it is not as clear as the dark explosion-proof film. The reason for this phenomenon is that although some films have good light transmittance, heat-absorbing agents or pigment particles are added. When light passes through these particles, it is reflected or refracted, causing a physical reaction. A sense of dizziness.
