Tempered glass is a type of safety glass that is strengthened through physical or chemical methods, with its core advantages reflected in significantly improved mechanical properties and safety.

• High Strength Characteristics: Its bending strength and impact resistance are several times higher than that of ordinary glass, with a load-bearing capacity 3 to 5 times greater than that of ordinary glass. Under the same thickness, it is less affected by impact forces.
• Safe Breakage Pattern: When broken, it shatters into uniform, small particles without sharp edges, greatly reducing the risk of injury to people. Therefore, it is widely used in scenarios with high safety requirements, such as automobiles and high-rise buildings.
• Excellent Thermal Stability: Its resistance to rapid cooling and heating is 3 to 5 times that of ordinary glass. It can withstand temperature differences of over 250 degrees (some sources mention no bursting at 150°C temperature differences), effectively preventing thermal breakage.

• Disadvantages and Maintenance Recommendations for Tempered Glass

  Inherent Defects

  • Spontaneous Breakage Risk: Due to internal stones, impurities, or uneven stress, the spontaneous breakage rate is approximately 1-3%.
  • Surface Irregularities: Slight unevenness exists, making it unsuitable for use as mirrors.

  Daily Maintenance Tips

  • Avoid Hard Impacts: Pay special attention to protecting the edges (the edges of tempered glass are relatively weak).
