Smell: after tearing the protective layer, the inferior film smells a pungent taste, while the high-grade film uses environmental protection glue, basically no smell, or there is a light glue smell.
Touch: high-grade film feels thick and smooth, inferior film is very soft and thin, lack of enough toughness, easy to wrinkle.
Rub: you can take a little alcohol or gasoline, wipe the surface of the film. Inferior film a wipe is easy to fade, high-grade film is not easy to fade.
How to choose your own car glass film:
Front gear: the transmittance of front gear is generally above 75%, so as to ensure the clarity of driving and ensure driving safety. The higher the transmittance, the more transparent the film, but at the same time the insulation performance and uv resistance will be reduced.
Side and rear block: there are many collocation of side and rear window patch.
1, pay attention to privacy can choose a low light transmittance model, the lowest light transmittance on the market is 5%, almost lying on the window can not see inside.
2, want to improve the heat insulation performance, you can choose infrared barrier rate, the total heat insulation rate is higher. Usually the heat insulation rate on the market can reach 60-70% or so, but to remind is: the heat insulation rate of good car glass film can not completely reduce the temperature rise in the car, can only alleviate, or slow down the speed of temperature rise.
3. If you want to improve safety, you can choose the explosion-proof film with higher price. This kind of film can effectively prevent the splashing of broken glass when the glass is broken.
4, of course, you can also choose to use the front screen model to stick to the side and back, so that it can play a certain effect of heat insulation and light resistance, while not affecting the lighting of the car space.
