UV absorbers are chemical additives used in plastics to protect them from the harmful effects of ultraviolet (UV) radiation. UV radiation can cause plastics to degrade over time, leading to color fading, brittleness, and reduced mechanical properties. UV absorbers help extend the lifespan of plastic materials by absorbing harmful UV rays and preventing them from causing these damages. https://www.sarex.com/fine/triazine-uv-absorbers-plastics
