TPU film is utilized in various fields, but there are not many cases where it is used in a visible form, because TPU film changes its form according to its use and purpose due to its ease of processing. Here are some examples of TPU films in use.

TPU films are especially suitable for a number of automotive seating applications such as:

• Lumbar support bladders: TPU films ensure good air retention properties
• Headrests and armrests: TPU film bonds well to polyurethane foam, making it an excellent choice for headrest and armrest applications. The film acts as a barrier between the foam and the fabric, creating a much more accurate production process and preventing moisture from getting into the foam
• Seat heating systems: TPU film bonds well to a number of non-woven materials, making it especially suited for automotive seat heating systems. Heating wires can be embedded into hotmelt film and sandwiched between two nonwovens for optimum heat management.
• Sunroof Shades :TPU films can be used as textile laminates for sun protection curtains in automotive sunroofs. These soft and elastic films are easily laminated to fabric, manage light, save weight and decrease volume. Covestro offers both flame retardant and non-flame retardant TPU films suited for different lamination processes. In addition, developmental grades are available that combine a high shading black layer with white or grey for more desirable aesthetics to match interior color schemes

Feature

TPU film is a film (sheet) directly extruded from thermoplastic elastomer resin, which is used in a wide range of industrial fields because of its excellent abrasion resistance, flexibility, oil resistance, chemical resistance, and other functional properties that can be achieved through the selection of raw materials and synthesis methods.
Widely known features of TPU film are as follows.

TPU film is attracting attention not only for its high mechanical strength, such as tensile and tear strength, and abrasion resistance, but also for its excellent oxygen permeability (gas barrier property) and water vapor permeability. TPU has the disadvantage of yellowing under the influence of ultraviolet rays, but by selecting and blending raw materials, TPU films with high transparency and resistance to yellowing (non-yellowing) are now available.
