12mm Clear/Low Iron Toughened Glass Panel
It is processed by heating 12mm clear float glass, 12mm low iron glass, 12mm tinted glass, or 12mm frosted glass to 650 degrees softening point, and then quenched rapidly. It creates tension inside the glass and compression outside the glass surface.
Heating Time
12mm clear/low iron tempered glass in Radiant furnace: 39s/mm, total 465 seconds~475 seconds
12mm clear/low iron toughened glass in Forced Convection furnace: 28s/mm, 275 seconds~285 seconds
12mm tinted/colored tempered glass in Radiant furnace: 35s/mm, 422 seconds~432 seconds
12mm tinted/colored toughened glass in Forced Convection furnace: 28s/mm, 330 seconds~340 seconds
Quenching Time
12mm toughened glass Quench Time=Glass Thickness^1.8=12mm^1.8=88s
Compression & Tension Zone
21% (2.52mm) up & down part with compression, 58% (6.96mm) middle part with tension.
Surface compression >90Mpa (over 13000Psi).

Features & Benefits
Flatness Quality
<0.2% local bow & <0.3% arc bow standard, with non-visual defects in the surface.
Flexibility
3~5 stable cooperative factories to guarantee lead time based on different requests.
One Stop Solution
From smaller size glass louver to giant glass 3660mm*18000mm toughened glass.
Safety
when 12mm tempered glass panel is broken, it will break into granularities to prevent series of injuries.
Strength
12mm tempered glass is about 4~5 times stronger than 12mm annealed glass.
Stability
12mm clear and low iron toughened glass can withstand 280℃ temperature variation.
Applications
