HC Chemical Network News: In recent years, the development of automotive interior film technology has made great progress. From February 6th to 7th, 2018, the "Folien+Fahrzeug" conference will be held in Hanover, Germany. The speech at this meeting will fully reflect this.
Dirk Pophusen, the technical director of the conference and a film specialist at Covestro, explained: “The trend of autonomous driving, the Internet and personalization has brought new challenges, and it has also created a new application for polycarbonate and thermoplastic polyurethane film. More opportunities."
Seamless integration of large 3D display
As digital and networked (interconnected automotive devices) continue to make progress, and as cars continue to shift to autonomous driving, the number of displays and touch screens inside the car will increase dramatically. The current trend is to seamlessly integrate large 3D displays onto dashboard surfaces, center consoles, doors and seat panels.
High-contrast images, as well as clear and easy-to-read information when lighting conditions are poor, are also important. The display cannot be reflective or glare (anti-glare). The double-cured film Makrofol ® HF developed by Covestro can be molded over a large area and is especially suitable for the trim of the display. Depending on the optical requirements, the display can be adjusted to high gloss or matt and resistant to chemical attack and scratches.
Makrofol ® film can also be used on 3D surface touch displays. In this way, the driver can control the display and its associated function keys by touching the screen without having to remove the line of sight from the road. This will improve the safety of driving.
Widely used TPU film
In addition, Covestro will introduce various potential uses of TPU film in automotive interiors.
Oliver Hennig is also a thin film expert at Covestro. In his presentation, he will introduce the use of TPU film and possible new applications in the future. He said: "The application of TPU film to automobiles is an area that has yet to be developed."
Covestro's Platilon ® TPU film can be used in multiple parts of the interior of a car, such as fabric slats for awning roller blinds, airbags for car seats supporting the waist, or foam coverings for noise reduction components.
Create decorative and lighting effects with flexible electronics
A new and promising field of application for TPU films is "flexible electronics." The thin film processor integrates flexible TPU films with various electronic devices such as trackers or sensors. Hennig said: "TPU film can also be integrated with LEDs. The resulting film laminate can form decorative parts with very complex geometric shapes and provide illumination."
Flexible electronic devices based on TPU films can be used in electric vehicles for large surface area radiant heating inside automobiles, and can replace the costly heating of conventional internal combustion engine exhaust gases. Hennipig said: "TPU films are extremely flexible and have good adhesion. For example, they provide good conditions for integrating the required conductor path electronics into the vehicle's facade panels."
