UV Resistance
UV resistance is the ability of a material to withstand damage or degradation caused by exposure to ultraviolet (UV) radiation from sunlight or artificial sources. Materials with good UV resistance are used in outdoor applications to prevent color fading, deterioration, or loss of mechanical properties over time.
