Tempered glass is produced by heating flat glass to just below its softening point and suddenly chilling it with jets of cold air. This process results in the outer surfaces being under powerful compressive stress and the interior standing under severe tensile stress. In consequence, the impact applied to the glass will be overcome by the compressional stress on the surfaces, ensuring safety of use.
Features:
- Tempered horizontally, eliminating the need for tong marks (hanging holes).
- The strength of tempered glass is approximately 5 times that of ordinary annealed glass.
- When broken by external force, it shatters into small, bean-sized granules, significantly reducing the risk of human injury.
- Can withstand rapid temperature changes (e.g., 5mm tempered glass can endure a temperature variation of approximately 200°C).
- Due to the risk of spontaneous breakage, tempered glass is recommended to undergo the Heat Soak Test (HST) to ensure greater safety in use.
Applications:
- Automobiles, trains, ships, architecture, furniture.
- Automatic doors, escalators, fireplaces, etc.
