8mm round shape flat polished edge tempered glass

• Tempered (toughened) glass is two or more times stronger than annealed glass
• When broken, it shatters into many small fragments which prevent major injuries
• This type of glass is intended for glass façades, sliding doors, building entrances, bath and shower enclosures and other uses requiring superior strength and safety properties
• Two different methods used to produce tempered glass:
  • Heat treating:
    • Where the annealed glass is subjected to a special heat-treatment in which it is heated to about 680°C and afterwards cooled
    • If it is cooled rapidly, the glass is up to four times stronger then annealed glass and its breaks into many small fragments (fully-tempered)
    • If it is cooled slowly, the glass is twice as strong as annealed glass and the fragments of the broken glass are linear and more likely to remain in the frame
  • Chemical strengthening:
    • Glass is covered by a chemical solution which produces a higher mechanical resistance
    • Chemically-strengthened glass has similar properties to thermal-treated glass
    • Product is not generally used for window glass, but more commonly seen in industries where thin, strong glass is needed
