TPU (thermoplastic polyurethane) film is widely used in various fields due to its excellent physical properties (such as high elasticity, wear resistance, oil resistance, low-temperature resistance, and tear resistance) and environmentally friendly features (recyclable and plasticizer-free). The following are some automotive applications of TPU film:

Automotive Industry
Interior Materials
Applications:
Seat Covers: TPU film is laminated with fabric or leather to create a wear-resistant, easy-to-clean seat surface.
Instrument Panel Trims: TPU film is vacuum-formed to create decorative parts with textures and luster, replacing traditional PVC.
Advantages: TPU film offers superior scratch and UV resistance compared to PVC and complies with ROHS environmental standards.
Sealing and Sound Insulation
Applications:
Door Seals: TPU foam film is used for door seals to reduce wind noise and water leaks.
Hood Sound Insulation: TPU/aluminum foil composite film blocks engine noise while also being heat-resistant (up to 120°C). Airbags
Applications: TPU film is used in the manufacture of side and curtain airbags. Due to its high strength and rapid inflation, it can deploy within 0.03 seconds in the event of a collision.
Seat Airbags
Applications: TPU film and 3D support materials together form automotive seat airbags, significantly enhancing the driver's driving experience.
Summary of the Core Advantages of TPU Film Applications
Performance Advantages
Elasticity and resilience: Suitable for products that require repeated bending or stretching (such as air cushions and sealing strips).
Abrasion resistance: Superior to rubber and PVC, suitable for high-friction applications (such as shoe soles and conveyor belts).
Chemical resistance: Oil and solvent resistant.
Environmental protection: Recyclable, non-toxic, and compliant with EU REACH and RoHS standards.
Processing flexibility: Supports a variety of welding methods, including hot pressing, high-frequency welding, and ultrasonic welding, and can be laminated with fabrics and metals.
With advances in material technology, TPU film is expanding towards higher performance (such as high-temperature resistance and electrical conductivity) and more niche applications (such as biodegradable TPU). It has enormous potential for future applications in cutting-edge high-end automotive applications.
