In new energy vehicles (NEVs), both TPU materials (Thermoplastic Polyurethane) and PC (Polycarbonate) have specific applications and advantages. However, they differ significantly in performance characteristics and usage scenarios.
TPU materials are primarily used in interior and exterior components, such as car seat covers, steering wheel covers, and door control panels. Due to its abrasion resistance, weather resistance, and high elasticity, TPU is ideal for adapting to the complex and dynamic environments of NEVs. Additionally, TPU is widely applied in paint protection films, window seals, and automotive parts such as brake hoses and braking system pipes. These properties make TPU materials highly durable and reliable in NEV applications.
PC (Polycarbonate) is known for its outstanding impact toughness, creep resistance, and thermal stability. It has a shrinkage rate of 0.5–0.7%, with an optimal wall thickness of 2–3.5mm. Adding glass fiber (GF) reinforcement can improve shrinkage resistance, mechanical strength, and heat resistance, making it more rigid when used at temperatures around 100°C. Annealing can also enhance internal stress resistance.
In NEVs, PC is commonly used in headlamp covers, wheel arch guards, and dashboard panels. Its excellent impact resistance and durability make it a preferred material for critical automotive components. By adding glass fiber, PC can further enhance its dimensional stability and mechanical performance, improving its overall durability and heat resistance.
Both TPU materials and PC serve distinct roles in NEVs. TPU is mainly used for high-elasticity and wear-resistant components. PC is preferred for high-strength and heat-resistant applications. Both materials play a crucial role in meeting the diverse material performance demands of the new energy vehicle industry.
