TPU Film for Automotive Seat Air Bladder
TPU film is increasingly used in automotive seat air bladder systems due to its excellent mechanical properties and chemical resistance. Unlike traditional materials, TPU (thermoplastic polyurethane) film offers high flexibility, puncture resistance, and air-tight sealing, which are critical for consistent inflation and deflation cycles in seat lumbar support and massage functions. Additionally, TPU film maintains performance across a wide temperature range and resists oils and sweat, ensuring long-term durability and passenger comfort in modern vehicle interiors.

Applied by high frequency welding.
TPU film is a non-hazardous item and should be handled with care during transportation. Avoid exposure to sunlight, rain, heat, or heavy pressure. Do not use hooks during loading and unloading to protect the packaging. The product must be stored in a cool, well-ventilated, dry place, protected from sunlight, rain, and high temperatures. Stacking height should not exceed three layers. The storage environment should be between 0°C and 30°C in a cool, dry place (humidity ≤ 70% RH).
Shelf Life: 12 months from the date of production.
TPU (Thermoplastic Polyurethane) automotive seat air bladder film is a core functional material used in pneumatic systems for seat lumbar support, massage, side bolster adjustment, and other functions. The film is made into air bladders through high-frequency welding, enabling support adjustment and massage functions during inflation and deflation cycles. Compared with traditional PVC materials, TPU film offers better environmental friendliness, flexibility, and durability.
It is polyether based.
