   Clear float glass is a high-quality flat glass manufactured via the advanced float process—a revolutionary production technology that involves pouring molten glass onto a bath of molten tin, allowing the glass to spread evenly and cool into a flat, smooth sheet. This process eliminates the surface irregularities common in traditional glass, resulting in a product with exceptional clarity, uniform thickness, and superior optical performance.With stable physical properties (Mohs hardness 6-7, bending strength ≥80 MPa), clear float glass offers reliable scratch resistance and structural stability, suitable for long-term use in high-traffic or demanding environments.

Main features:

1. Basic Physical & Mechanical Properties

Parameter Index (for 5mm thickness)
Density 2.5 g/cm³
Mohs Hardness 6-7 (scratch-resistant to ordinary objects)
Bending Strength ≥ 80 MPa
Elastic Modulus 70-75 GPa
Thermal Conductivity 0.8 W/(m·K)
Thermal Expansion Coefficient (9.0±0.2)×10⁻⁶/°C (20-300°C)
2. Surface & Dimensional Standards

- Surface Quality: Complies with GB/T 11614-2022 Grade A / ISO 12543-2 Class 1 (no obvious bubbles, scratches, or inclusions)
- Flatness Tolerance: ≤ 0.3mm/m (ensures stable processing performance)
- Dimensional Tolerance: Length/Width ±1mm (common sizes); Thickness ±0.2mm (2-6mm) / ±0.3mm (8-19mm)

3. Processing Adaptability

- Suitable for: Cutting, tempering, heat strengthening, laminating, insulating, silk-screen printing, coating (low-e, silver mirror, etc.)
- Temperature Resistance: Can withstand 200-300°C short-term heat (before tempering); Tempered products can resist up to 280°C

4. Optical Performance

- Light Transmittance: ≥ 89% (uncoated, 5mm); ≥ 91% (ultra-clear float glass, 5mm)
- Haze: ≤ 0.1% (ensures high clarity, no visual distortion)
- Refractive Index: 1.52 (at 550nm visible light)


5. Environmental & Safety Indicators

- Heavy Metal Content: Complies with RoHS/REACH standards (environmentally friendly, non-toxic)
- Sound Insulation: ≥ 30 dB (5mm single sheet; higher with insulating structure)

Applications:

1. Doors & windows (residential/commercial, custom-sized)
2. Building facades & architectural curtain walls

3. Mirror coating (high-end silver mirror substrates)
4. Greenhouses, solar collecting roofs, large ornamental fish tanks, etc.
5. Household electrical appliances (e.g., premium appliance glass components)
6. Custom furniture & interior decoration
7. PV modules & solar water heater glass covers
8. Exquisite craftworks & decorative lighting accessories
