TPU Composite Film:
TPU material serves as the core component of automotive seat air bladders, offering high strength, toughness, and exceptional abrasion resistance. It withstands long-term, high-frequency inflation/deflation cycles without rupture. Through a lamination process with 3D mesh fabric, the TPU composite film forms a multi-layered structure that balances structural integrity and breathability, ensuring stable airflow channels even under seat pressure.
3D Mesh Fabric:
As the supporting skeleton of the air bladder, this material employs a three-dimensional weaving process to create a porous 3D network structure. With a porosity exceeding 85% and precisely engineered pore parameters, it enables efficient airflow conduction and uniform dispersion. The 3D mesh fabric boasts a compression rebound rate over 95%, allowing rapid shape recovery after compression to prevent airflow blockage caused by prolonged pressure.
Nonwoven Fabric:
Acting as the contact layer, the nonwoven fabric bonds with the TPU film and mesh fabric via thermal lamination. Its surface is specially treated for a skin-friendly texture, while optimized fiber architecture enhances breathability. Additionally, the nonwoven layer provides filtration, intercepting particles larger than 0.1mm in diameter to prevent contaminants from entering the ventilation system and causing malfunctions.
