Lightweight design is future trend of automotive industry. High performance plastics are the best way to replace metal substrates. The industry continues to improve the plastic composite materials physical properties to exceed the rigidity of metal substrates, thereby to fulfill lightweight and safety requests of automotive industry. However, plastics are sourcing from polymer which is easy to influenced by outdoor environments. Yellowing, chalking will impact plastics physical properties. Everlight Chemical provides high weather-resistance solutions for automotive plastic parts which will minor change in transparency and initial colors.
