15mm Thick Toughened Glass
It is processed by heating 15mm clear float glass, 15mm low iron/extra clear glass, or 15mm frosted/acid-etched glass to 650 degrees softening point, and then quenched rapidly. It creates tension inside the glass and compression outside the glass surface.
15mm clear/low iron/extra clear/ultra clear/Starphire/super clear tempered glass in Radiant furnace: 39s/mm, total 580 seconds~590 seconds
15mm clear/low iron/extra clear/ultra clear/Starphire/super clear toughened glass in Forced Convection furnace: 28s/mm, 412 seconds~422 seconds
15mm toughened glass Quench Time=Glass Thickness^1.8=15mm^1.8=131s
Compression & Tension Zone
21% (3.15mm) up & down part with compression, 58% (8.70mm) middle part with tension.
Surface compression >90Mpa (over 13000Psi).
15mm Toughened Glass Standard & Certificate
ASTM C1048 standard, SGCC certificate
EN12150 standard, CE certificate
Australia & New Zealand
AS/NZS2208-1996 standard, AS/NZS 2208 certificate
Features & Benefits
<0.2% local bow & <0.3% arc bow standard, with non-visual defects in the surface.
3~5 stable cooperative factories to guarantee lead time based on different requests.
From smaller size glass louver to giant glass 3660mm*18000mm toughened glass.
when 15mm tempered glass panel is broken, it will break into granularities to prevent series of injuries.
15mm clear/low iron toughened glass is about 4~5 times stronger than 15mm annealed glass.
15mm clear and extra clear toughened glass can withstand 280℃ temperature variation.
