Is Car Glass Tempered Glass?
1 Answers
Car glass mainly falls into the following three categories: laminated glass, tempered glass, and zoned tempered glass. Tempered glass is used for car windows due to the following reasons: 1. High mechanical strength and impact resistance. The impact resistance of tempered glass is 5-8 times that of ordinary glass of the same thickness; high bending strength, with tempered glass being 3-5 times stronger than ordinary glass. 2. Excellent thermal stability. Thermal stability refers to the glass's ability to withstand drastic temperature changes without breaking. Tempered glass can withstand temperature changes ranging from 150-320°C, while ordinary glass can only handle 70-90°C. For example, if tempered glass is placed on 0°C ice and molten lead at 327°C is poured onto it, the glass will not shatter. 3. Good safety performance. When tempered glass breaks, it fragments into small, honeycomb-shaped blunt particles, reducing the risk of injury.
