Clear Tempered Glass Technical Parameters
​​Category​​ ​​Parameter​​ ​​Standard Example​​ ​​Technical Notes​​
​​Basic Properties​​ Glass Type Clear Tempered, Ultra-Clear, Low-E Coated, Patterned, Curved Customizable colors, patterns, and coatings
Thickness Range (mm) 4~19 (Common: 5/6/8/10/12/15/19) Thickness tolerance: ±0.2mm (GB 15763.2)
​​Mechanical Performance​​ Surface Compressive Stress (MPa) ≥90 (Standard) Heat-Strengthened: 24~69 MPa
≥150 (High-Strength)
Bending Strength (MPa) 4–5x Annealed Glass Test method: ASTM C1048
(5mm: ≥70; 8mm: ≥90)
Impact Resistance (mm steel ball/height) 1040g ball dropped from 1m height (no break) Complies with GB 17841 safety requirements
​​Safety Features​​ Fragmentation Pattern >40 fragments in 50×50mm area (5mm) Crumbles into granular pieces with blunt edges
Min. fragment weight: ≤0.5g (GB 15763.2)
Thermal Shock Resistance (ΔT) Resistant to thermal shock of 200°C No cracks (Test per GB 15763.2)
​​Optical Properties​​ Light Transmittance (%) Clear: ≥89% (4mm) Low-E coating adjusts transmittance to 50%~80%
Ultra-Clear: ≥91% (6mm)
UV Blocking Rate (%) Clear: <60 Depends on coating type
Low-E: ≥90
Dimensions Min. Size 300×300 mm Most sizes customizable
Max. Size 3300×13000 mm
Minimum Hole/Notch Margin Edge distance ≥2×glass thickness (e.g., 5mm glass → ≥10mm) Prevents edge stress concentration
​​Heating Stage​​ Furnace Temperature (°C) 600~720 (near softening point) Heating time: 170~200 sec/mm (≤6mm), 290~380 sec/mm (≥8mm)
​​Quenching Stage​​ Cooling Air Pressure (%) 4mm: 95~100% Rapid cooling induces surface compressive stress
10mm: 85~90%
​​Edge Treatment​​ Grinding/Polishing CNC precision grinding (R-angle ≤0.5mm) Reduces spontaneous breakage risk
Mirror/matte finish
​​Special Treatment​​ Heat Soak Test (HST) 260°C±10°C for ≥2 hours (mitigating spontaneous fracture) Lowers breakage rate from 0.3% to <0.1% (GB 15763.2)
​​Application​​ ​​Recommended Configuration​​ ​​Certifications​​
​​Building Facades​​ 8~12mm clear/ultra-clear, U-value ≤1.8 EN 12150, ASTM C1048, GB 15763.2
​​Furniture/Partitions​​ 5~8mm patterned/frosted, fragment count ≥40 CNS 11227 (Taiwan), JIS R3205 (Japan)
​​Automotive Side Windows​​ 4~5mm curved, visible light transmittance ≥70% (GB 9656) ECE R43, ISO 3537
​​Solar Panels​​ 3.2~4mm ultra-clear textured, transmittance ≥91.5% IEC 61215 (UV/thermal cycling tests)
