Our premium PC sheets feature adual-sided co-extruded UV protection layer,

integrated seamlessly during manufacturing (not applied post-production, so no peeling or flaking). 

This UV barrier blocks 99.9% of harmful ultraviolet rays, inhibits photo-oxidation,and protects the PC molecular chain from degradation.



 Anti-yellowing service life reference:  

Outdoor use: Maintains stable light transmission for 10–15 years with minimal yellowing, 

                            backed by a 10-year major yellowing warranty.  

Indoor use: Minimal color change, with a service life exceeding 20–30 years.  

Passes ASTM and ISO accelerated weathering tests, featuring low (yellowing index) and slow light transmission decay.


Other key advantages:  

Made from virgin PC material—no recycled fillers  

High impact resistance, 250 times stronger than glass, highly resistant to breakage  

Wide temperature tolerance: -40°C to +120°C  

Easy to cut, bend, drill, and process  

Available in transparent, textured (lychee grain), frosted finishes,thickness and dimensions customizable  


Ideal for applications such as architectural partitions, light diffuser panels, skylights, machinery enclosures, window privacy screens, signage, outdoor canopies, and more.
