PC Film Sheets: Building a Core Barrier for the Safety and Intelligence of New Energy Vehicles

Amid the wave of lightweighting and intelligent upgrading in new energy vehicles, polycarbonate (PC) films and sheets have become core supporting materials, with market demand steadily climbing. Data shows that PC material usage per new energy vehicle is 80%-120% higher than that of traditional fuel vehicles, with films and sheets accounting for over 30%, making them indispensable in fields such as battery systems and smart cockpits.

Their application scenarios are extending toward high-end core areas, with performance requirements continuing to rise. In battery systems, PC flame-retardant insulating films must meet UL94 V-0 flame retardancy and withstand high temperatures of 120-150℃ to solidify the safety defense line; on the smart cockpit side, PC/PMMA composite films are suitable for components such as central control screens and ARHUD light guide plates. Scenarios such as charging piles and LiDAR covers also impose stringent requirements on their weather resistance and impact resistance.

Technologies such as multilayer co-extrusion and precision coating are core competitive barriers, and domestic enterprises are breaking through automotive-grade technology monopolies to build differentiated advantages such as halogen-free flame retardancy. With the growing penetration of new energy vehicles and the popularization of high-voltage fast charging technology, high-temperature-resistant and recyclable PC films and sheets will embrace a broader market, empowering automotive safety and intelligent upgrading.
