3.2mm 4mm Low Iron Solar Toughened Cover Glass for Solar Collectors and Solar Energy
products introduction:
Solar water heater glass is a high-performance, specialized glass designed for the core components of solar water heating systems. It features excellent light transmittance (typically over 90%) to maximize the absorption of solar radiation, ensuring efficient conversion of solar energy into heat for water heating.
Speicifation:
| thickness tolerance | ±0.2mm |
| Dimension tolerance | ±1mm |
| Diagonal difference | ≤0.1-0.2% |
| Overall bow/warp | <0.2% |
| Local warp | ≤0.3mm/300mm |
| Fragmentation test | ≥40 particles within 50x50mm |
| Scratch hardness | 4~5 |
| poisson's ratio | 0.2 |
| Tensile strength | 42n/mm2 |
| Pressure resistance | 700-900m/mm² |
| Standard size | 1220X2440mm 1500X2000mm, 1830X2440mm (customer size available) |
| Edge processiong | seamed/ground edges(deburred,no sharp corners) |
| Tempering grade | Fully Tempered |
Features:
1. Superior Light Transmittance: ≥90% (low-iron type ≥93%) visible light transmittance maximizes solar energy absorption, boosting the heating efficiency of solar water heater systems.
2. Enhanced Mechanical Strength: Tempered processing ensures surface hardness ≥7H (Mohs scale) and excellent impact resistance, preventing breakage from outdoor impacts (e.g., hail, debris).
3. Exceptional Weather Resistance: Advanced coating and premium glass material resist UV radiation, extreme temperatures (-30℃ to +350℃), humidity, and salt spray, maintaining performance for ≥10-15 years outdoors.
4. Safety Compliance: Fully tempered structure breaks into small, blunt-edged fragments (no sharp shards), meeting international safety glass standards (ASTM C1048/EN 12150) for safe installation.
5. Optional High-Performance Coatings: AR coating reduces reflectivity ≤4% for better light absorption; Low-E coating cuts heat loss (emissivity ≤0.12) to improve energy efficiency.
6. Customizable Specifications: Flexible thickness (3-8mm), sizes (standard/custom), and edge processing (seamed/ground) to fit flat-plate, vacuum tube, and other solar heater collector models.
7. Eco-Friendly & Standard-Compliant: RoHS/REACH certified, made of non-toxic materials; complies with ISO 9050 for solar optical properties, suitable for global residential/commercial/industrial applications.
