What Causes Sudden Spontaneous Breakage of Car Glass?

[DeAxel]

Reasons for sudden spontaneous breakage of car glass: 1. Quality issues with the glass itself: Car glass is tempered glass, which has excellent impact resistance and bending strength and is less likely to cause injury when broken. However, spontaneous breakage can occur. According to national standards, there is a possibility of three per thousand spontaneous breakages per square meter. 2. Uneven heating and cooling of the glass: When there is excessive variation in temperature, stress deformation can occur in the glass, leading to breakage. 3. Poor-quality or improperly applied window film: Low-quality films often contain excessive amounts of absorbers, causing all the heat to be absorbed by the glass, which raises the glass temperature and increases the likelihood of spontaneous breakage.
