Characteristics of PC Sunshine Board

1. Transparency: The transmittance of PC solar panels can reach 89%, which is comparable to glass. UV coated boards will not produce yellowing, 

fogging, or poor light transmission when exposed to sunlight. After ten years, the loss of light transmission is only 10%, 

while the PVC loss rate is as high as 15% -20%, and the glass fiber loss rate is 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. It can be dropped two meters below a 3kg hammer without cracks, earning it the reputation of "unbreakable glass" and "sound steel".

3. UV protection: One side of the PC board is co extruded with a UV resistant coating, and the other side is treated with anti condensation, 

integrating UV resistance, thermal insulation, and anti fog droplet functions. 

It can block UV rays from passing through and is suitable for protecting valuable artworks and exhibits from UV damage. 

4. Lightweight: With a specific gravity only half that of glass, it saves on transportation, unloading, installation, and supporting frame costs. 

5. Flame retardant: According to the national standard GB50222-95, PC polycarbonate panels are classified as Class B1 for flame retardancy. 

The ignition point of the PC board itself is 580 ℃, and it will self extinguish after leaving the fire. When burning, it will not produce toxic gases and will not promote the spread of fire. 

6. Flexibility: According to the design drawings, cold bending can be used on the construction site to install arched, semi-circular roofs and windows. 

The bending radius is 175 times the thickness of the board, and it can also be hot bent. 

7. Soundproofing: The sound insulation effect of PC solar panels is significant, with better sound insulation than glass and acrylic panels of the same thickness. 

Under the same thickness conditions, its sound insulation is 5-9DB higher than glass. Internationally, it is a material for highway noise barriers. 

8. Energy saving: Keeping cool in summer and insulated in winter, PC polycarbonate panels have a lower thermal conductivity (K value) than ordinary glass and other plastics, 

with a thermal insulation effect 7% -25% higher than equivalent glass, and insulation up to 49%. 

This greatly reduces heat loss and is an environmentally friendly material used in buildings with heating equipment. 

9. Temperature adaptability: The PC board does not undergo cold brittleness at -40 ℃, does not soften at 125 ℃, 

and its mechanical properties do not show significant changes in harsh environments.
