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 better than acrylic?
Polycarbonate Material vs Acrylic Material. Generally speaking, acrylic sheeting is shinier and polycarbonate sheet is stronger. Acrylic and polycarbonate both weigh less than half of what a comparably sized piece of glass weighs yet they are both much stronger than glass. Both materials are also very easy to clean.
