Question: Does polycarbonate degrade in sunlight?

However, bisphenol A polycarbonate is susceptible to photodegradation under ultraviolet (UV) radiation, which causes breakdown of the material, leading to yellowing, loss of toughness and embrittlement.

Is polycarbonate affected by sunlight?

Polycarbonate panels are resistant to extreme temperature either hot or cold, sunlight, snow, rain, and impact. This enables the panels to last for many many years without fading or discoloring while also remaining damage free from any various impacts over the years.

Does polycarbonate yellow in the sun?

Unlike acrylic though, the colour clarity of polycarbonate does diminish over time and will adopt a yellow hue with prolonged exposure to the UV rays.

Is polycarbonate UV resistant?

Like acrylic, polycarbonate has some cons to consider. It is typically not a shiny material, but it can be polished. Although it resists cracking and chipping, it dents and scratches easily. It has good clarity, but it is not UV resistant and unless coated it will yellow over time.

Does polycarbonate degrade over time?

Limitations of Polycarbonates Mechanical properties degrade after prolonged exposure to water at over 60°C. Attacked by hydrocarbons and bases. Proper drying before processing is needed. Yellows after long exposure to UV.
