Tedlar®: the PVF benchmark for long-term protection

Tedlar® is a film made of polyvinyl fluoride (PVF), a highly inert fluoropolymer. Its chemical structure imparts high resistance to acids, bases, solvents, cleaning agents, UV, hydrolysis, and external pollutants. The film is manufactured without plasticisers, which limits phenomena such as migration, embrittlement, and premature ageing.

Tedlar® films are available in clear, pigmented, oriented, unoriented, single-coated, double-coated, or uncoated versions. Typical thicknesses range from 13 to 100 µm, with formats adapted for surface protection, photovoltaics, industrial lamination and release applications.

The material performs -70 °C to +105 °C in continuous use and can withstand short peak loads of up to 204 °C in transformation or as a release agent. It also exhibits lower moisture absorption than 0,5 % for most grades and an optical transmission up to 93 % for the transparent versions.

Tedlar® range available from ADDEV Materials

ADDEV Materials distributes and transforms several configurations of Tedlar® films according to colour, thickness, surface treatment, gloss level and film orientation. The grade choice depends on UV exposure, adhesion requirements, the substrate to be protected and the transformation process.

FAQ — Tedlar® PVF Film and Industrial Applications

Tedlar® film is a PVF (polyvinyl fluoride) fluoropolymer film developed by DuPont to protect surfaces from UV, moisture, solvents, cleaning agents, and outdoor weathering. It is used as a protective film or barrier film in photovoltaics, transportation, aeronautics, electronics, and construction.

The difference depends on the main constraint. Tedlar® PVF is recommended for UV, chemical, and outdoor resistance. Kapton® polyimide is suitable for high temperatures and harsh electrical insulation. Mylar® PET offers a good cost/performance compromise for standard electrical insulation and applications less exposed to UV.

A PVF film such as Tedlar® offers better resistance to UV rays, hydrolysis, solvents and cleaning agents than a standard PET film. For long-term outdoor exposure, PVF film minimises the risks of yellowing, cracking, chalking and loss of mechanical properties.

Tedlar® film typically operates from -70 °C to +105 °C in continuous use. It can withstand short peaks up to 204 °C during certain processing operations or release applications. The grade selection must, however, be confirmed according to the thickness, the laminated support and the mechanical stresses.

Yes. PVF Tedlar® is highly inert and resistant to a wide variety of solvents, acids, bases, cleaning agents, stains, hydrocarbons, and environmental contaminants. This resistance explains its use in frequently cleaned surfaces, exterior panels, and anti-graffiti films.

Yes, provided the correct surface treatment is selected. An untreated Tedlar® film has low surface energy and adheres poorly. Single-sided or double-sided treated versions create chemically active sites which improve adhesion with adhesives, resins, metals, textiles or polymer substrates.

A transparent film is chosen for optical applications or discreet protection. A pigmented white film is used for UV stability, opacity, and solar backsheets. A treated film is recommended for lamination or adhesion. An untreated film is suitable for release or low-adhesion applications.

The main applications are photovoltaic backsheets, anti-graffiti coatings, surface protection in transport, aeronautical decorative films, protection of electronic components, and exterior laminates. The common factor is long-term exposure to UV rays, moisture, or chemical agents.

Yes. ADDEV Materials transforms Tedlar® films into slitted rolls, sheets, die-cut parts, laminates or kits. Available operations include slitting, rotary die-cutting, CNC cutting, laminating, converting and kitting. The format is defined according to customer line, positioning and integration constraints.

The key parameters are the exposure environment, temperature, chemical agents, target service life, thickness, colour, adhesion requirements, substrate type, final format, and assembly method. This data allows for the choice between treated, untreated, transparent, pigmented, oriented, or non-oriented film.
