- Tedlar® PVF Features in Aerospace Applications
DuPont™ Tedlar® protective film offers attractive, easy-to-clean, scuff-resistant surface protection to aircraft interiors. Tedlar® films are lightweight, have excellent conformability and offer superior resistance to harsh cleaners, chemicals and solvents, eliminating the need for repainting and reducing maintenance costs to help provide every passenger a fresh look on every flight.
The proven performance of Tedlar® film has made it the aircraft standard to which other materials used in the industry are measured. Tedlar® film meets or exceeds Federal Aviation Administration (FAA) and European Union Aviation Safety Agency (EASA) standards.
Design flexibility
Tedlar® film gives airlines maximum interior design flexibility to create passenger areas that are attractive and easy to clean. Tedlar® films can be embossed and printed, enabling the use of many unique texture designs and can be tailored to various gloss levels, thicknesses and finishes.
Fade resistant
Tedlar® film is available in an array of fade-resistant colors to match the look of your aircraft. If necessary, the colors can be matched long after the initial installation. Transparent Tedlar® film is also available as an excellent overlaminate for printed patterns.

Technical Details & Test Data
- Resistance to Bacteria
Bacterial growth is also not supported by Tedlar® PVF films which are formulated without plasticizers, processing aids or other additives that can become a nutrient source for microbes. This was demonstrated using ISO 846:2019 Method C: Evaluation of the Action of Microorganisms – Resistance to Bacteria. Several Tedlar® PVF films were tested, along with DuPont™ Tedlar™ Wallcovering. They are listed in Table 4.
Samples were placed on agar that was previously inoculated with Pseudomonas aeruginosa at the desired concentration and covered with additional inoculated agar. Negative control samples were also prepared with non-inoculated agar to facilitate comparison to inoculated samples. The samples and control were incubated for 28 days at 28-30 ˚C and evaluated for visible evidence of growth. The results for all the Tedlar® PVF films and DuPont™ Tedlar™ Wallcovering showed the same result; there was no growth on or around all five replicate samples and therefore the specimens do not contain nutritive components for this bacterium. This is illustrated in Figures 4 and 5 for the transparent Tedlar® PVF film and the wallcovering.
