What are the methods for choosing automotive explosion-proof film?
2 Answers
Automotive explosion-proof film should be selected based on the following methods: choose a film with good light transmission that does not obstruct visibility. The functions of explosion-proof film include: 1. Heat insulation and cooling: It can reduce the overheating phenomenon inside the car caused by sunlight exposure, keeping the interior cool while also reducing air conditioning consumption; 2. UV protection: While ultraviolet radiation has sterilizing effects, it can also harm human skin. Explosion-proof film effectively blocks UV rays, protecting passengers' skin; 3. Preventing glass cracking and interior fading: Besides harming the owner's skin, prolonged direct sunlight can cause the car's interior to crack and fade. Explosion-proof film also helps maintain the car's interior and prolong its service life.
When choosing automotive explosion-proof film, I prioritize practical performance. First, visit an authorized store to test the heat insulation effect: place a sample under a heat lamp and feel the temperature difference with the back of your hand through the film. A good film should provide a noticeable heat-blocking sensation. The light transmittance of the front windshield should not be less than 70%, otherwise, it won’t pass the annual inspection and will affect nighttime visibility. Choose a UV blocking rate of over 99% to protect the interior from fading. The shade of color depends on personal preference—I prefer light gray as it doesn’t obstruct rearview mirror visibility. Opt for a brand that uses magnetron-sputtered metal film, which has a strong magnetic attraction and won’t interfere with mobile phone signals. It’s best to choose a branded film with a warranty card, where the electronic warranty can be verified by scanning a QR code, to avoid being sold outdated products. For installation, find a professional shop with a dust-free environment, and avoid opening windows for three days after application to prevent displacement.
