Thermoplastic Polyurethane (TPU) film is an ideal material for car seat lumbar support airbags due to its excellent flexibility, high tensile strength, and superior air-holding capability. Unlike traditional rubber or PVC films, TPU offers better resistance to abrasion, oils, and extreme temperatures, ensuring long-term durability and consistent performance in automotive environments. Its lightweight nature and ability to maintain elasticity under repeated inflation and deflation cycles make it particularly suitable for dynamic lumbar support systems. Additionally, TPU film can be easily heat-sealed or welded to form airtight bladders, providing reliable and comfortable ergonomic support for drivers and passengers.
