Characteristics of PC double-layer sunlight panels

1. Light transmittance: The light transmittance of PC panels can reach 89%, comparable to glass. The UV-coated panels do not yellow, haze, or lose light transmission under sunlight, with only 6% light loss after ten years, while PVC has a loss rate of 15%—20%, and fiberglass ranges from 12%-20%.

2. Impact resistance: The impact strength is 250-300 times that of ordinary glass, 30 times that of acrylic sheets of the same thickness, and 2-20 times that of tempered glass. A 3kg hammer dropped from two meters shows no cracks, earning the titles of "shatterproof glass" and "ring steel".

3. UV protection: One side of the PC panel is coated with a UV-resistant coating, while the other side has anti-condensation treatment, combining UV resistance and thermal insulation with drip prevention. It can block UV rays, making it suitable for protecting valuable artworks and exhibits from UV damage.

4. Lightweight: It has a specific gravity of only half that of glass, saving costs in transportation, handling, installation, and support framing.

5. Flame retardant: According to national standard GB50222—95, PC panels are classified as flame-retardant grade B1. The ignition point of PC panels is 580°C, and they self-extinguish after the flame is removed, without producing toxic gases during combustion and not promoting the spread of fire.

6. Flexibility: Can be cold bent on-site according to design drawings to form arch shapes, semi-circular roofs, and windows. The minimum bending radius is 175 times the panel thickness, and it can also be hot bent.

7. Sound insulation: PC panels exhibit significant sound insulation, providing better acoustic insulation than glass and acrylic sheets of the same thickness. Under the same thickness conditions, the sound insulation of PC panels is 3—4DB higher than that of glass. They are used as materials for highway sound barriers internationally.

8. Energy saving: Keeps cool in summer and warm in winter, PC panels have a lower thermal conductivity (K value) than ordinary glass and other plastics, with insulation effectiveness 7%—25% higher than that of equivalent glass, achieving insulation up to 49%. This significantly reduces heat loss, making them suitable for buildings with heating equipment and classifying them as environmentally friendly materials.

9. Temperature adaptability: PC panels do not become brittle at -100°C and do not soften at 135°C, maintaining their mechanical and physical properties without significant changes in harsh environments.

10. Weather resistance: PC panels maintain stability across various physical indicators within the temperature range of -40°C to 120°C. In artificial climate aging tests lasting 4000 hours, the yellowing degree is 2, and the light transmittance reduction is only 0.6%.

11. Condensation prevention: When the outdoor temperature is 0°C and the indoor temperature is 23°C with indoor relative humidity below 80%, the inner surface of the material does not condense.
