As LED/laser headlights proliferate, lens materials face stringent demands: ultra-high light transmission (>92%), UV resistance, impact strength, and complex moldability. Silicone resins are replacing traditional polycarbonate (PC) in premium headlights due to their extreme temperature stability (-50°C to 200°C) and processability.
Their weather resistance prevents yellowing/cracking, maintaining optical performance long-term. Models like Tesla Cybertruck and Xiaomi SU7 use silicone resin lenses for unique designs and reliability. Suppliers (Wacker, Dow) are developing lower-haze, higher-strength formulas to enable smarter, sleeker lighting.
