Frosted Glass Sheets – Technical Specifications & Application Guide​​

Frosted glass sheets are translucent surface-modified glass products designed to provide privacy while maintaining light transmission. These undergo specialized treatments to create permanent light-diffusing properties through surface etching or interlayer techniques.

​​Manufacturing Processes & Technical Variants​​

1. ​​Acid-Etched Frosting​​

   • Hydrofluoric acid treatment (0.1-0.5mm penetration depth)

   • Surface roughness: 3-8μm Ra

   • Light transmission: 50-75%

   • Standard thicknesses: 3mm, 5mm, 6mm (±0.15mm)

2. ​​Sandblasted Frosting​​

   • Aluminum oxide abrasive blasting (80-120 grit)

   • Creates deeper texture (0.2-1.0mm profile)

   • Customizable pattern resolution: 10-50 DPI

   • Matte finish with 40-70% haze

3. ​​Ceramic Frit Frosting​​

   • Silica-based enamel firing (600-700°C)

   • Permanent baked-on coating

   • UV stability: <1% degradation/year

4. ​​Interlayer Frosting​​

   • PVB or EVA laminated diffuser films

   • Maintains smooth tactile surface

   • Impact-resistant safety properties
