What is the function of automotive explosion-proof film?

When PET material with a thickness greater than 1.5 mil is used as the base material, the film has a certain safety protection effect—referred to as a safety film. When the thickness exceeds 6 mil, the film also has a certain protective effect against shock waves—referred to as an explosion-proof film. For detailed information, please see the following: 1. Function of explosion-proof film: When ordinary glass breaks, it forms sharp fragments of varying sizes, with sharp edges that can easily injure people, even fatally. Tempered glass is much safer than ordinary glass, breaking into uniform polygonal particles no larger than 15 mm, which generally do not cause direct harm. However, when it falls from a height or is subjected to impact force, it can gain acceleration and scatter, potentially causing injury or death. If safety explosion-proof film is installed, the broken glass will firmly adhere to the film, preventing it from scattering and causing harm. 2. Certain anti-theft effect: When explosion-proof film of a certain thickness is applied, significant effort and time are required to break the glass with tools like hammers or bricks, and the process produces loud noises. Therefore, safety explosion-proof film also has a certain deterrent effect against malicious intrusion and theft.
I'm always most concerned about safety when driving, especially when with family and children. The main function of car explosion-proof film is to prevent glass from shattering and flying in the event of an accident, significantly reducing the risk of injury to passengers. For example, last summer, a bird hit the front windshield on the highway. Fortunately, the film was applied, and the glass didn't shatter into pieces, keeping the whole family safe. Besides safety, it also provides sun protection and heat insulation, reducing the rise in interior temperature during hot weather and saving fuel by reducing the need for air conditioning. Additionally, it blocks UV rays to protect skin and interior materials, preventing fading and aging, while also enhancing privacy by making it difficult to see inside from the outside. I think this is particularly important for city driving. Overall, applying a good film is a cost-effective investment, especially for families with children—safety comes first.
