Photo-stabilization refers to the process of enhancing the resistance of polymers and other materials to degradation caused by exposure to ultraviolet (UV) radiation. This is crucial for extending the lifespan and performance of materials that are subjected to sunlight or other UV sources, preventing issues like discoloration, loss of mechanical properties, and chain scission. It involves the incorporation of stabilizers or additives that absorb harmful UV rays or scavenge free radicals formed during degradation.
