Tempered glass is made by heating flat glass to just below its softening temperature and suddenly chilling it with jets of cold air. It results the outer skins under powerful compressive stress and the interior with severe tensile stress. In consequence, the impact applied to the glass will be overcome by the compressional stress on the surfaces to assure safety of use.
‧No tong marks on the glass as TGI adopts the horizontally tempering process.
‧5 times harder than ordinary annealed glass.
‧Once breakage occurs, the glass disintegrates into small cubical fragments which are relatively armless
to human body.
‧It withstands abrupt change of temperature. For example, a piece of 5mm tolerate the temperature
variations within the range of 200°C.
‧Tempered glass should under go heat soak test to improve safety in use.
