Heat
Strengthened Glass
Heat strengthened glass is made
by evenly heating flat glass to
approximately 620°C. The ceramic
roller transmits glass at a stable
speed to ensure an even temperature
and optical performance. Heat
strengthened glass has similar
production process to that of
tempered glass, except for a longer
chilling duration.

Benefits
| • |
The
strength and resistance
to temperature changes
of heat strengthened
glass is two times
better than that of
the annealed glass
at same thickness. |
| • |
Heat
strengthened glass
has the same features
of annealed glass
like hardness, elongation,
polarization and resistance
to etching. |
| • |
Heat
strengthened glass
breaks into large
pieces, as shown in
Figure.
1. Influencing
factors are impact
strength, breaking
point and glass temperature.
Figure.1
|
|
| • |
In
comparison with tempered
glass, heat strengthened
glass is not easily
broken spontaneously. |
| • |
After
manufactured, it is
impossible to do any
of cutting, drilling,
grinding, frosting
and etching. |
