Le Tedlar® film refers to the PVF (polyvinyl fluoride) fluoropolymer film range developed by DuPont to protect surfaces exposed to UV light, moisture, solvents, and harsh outdoor environments. ADDEV Materials distributes and transforms Tedlar® films for the photovoltaic, transport, aeronautics, electronics, and industrial protection markets.
Each project can be customised via our converting capabilities: slitting, cutting, laminating, bonding, surface treatment, and kitting. The aim is to deliver a PVF film in the right format, with the correct adhesion treatment, and integration that is compatible with your industrial process.
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® is selected when outdoor durability, chemical resistance, and aesthetic stability are a priority. Its performance meets the demands of surfaces exposed to sunlight, cleaning agents, solvents, moisture, and thermal cycling.
Chemical resistance — solvents, acids, bases
Operating range: -70 °C to +105 °C

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.
| Reference / type | Technical description | Typical thicknesses | Main applications |
|---|---|---|---|
| Tedlar® TTR | Transparent PVF film, available in a high-gloss or surface-treated version | 25 – 100 µm | Optical protection, exposed surfaces, photovoltaic, signage |
| Tedlar® TWH | White PVF film, pigmented, high UV stability, and good opacity | 25 – 100 µm | Solar backsheet, outdoor panels, transport, UV protection |
| Tedlar® treated one side | Activated surface for improved adhesion with adhesives, resins or laminated supports | 13 – 100 µm | Industrial lamination, adhesive bonding, durable substrate protection |
| Tedlar® treated 2 sides | Double treatment for multi-layer complexing and technical assemblies | 25 – 100 µm | Composite structures, barrier films, functional laminates |
| Untreated Tedlar® | Inert fluoropolymer surface, low natural adhesion | 25 – 75 µm | Release, mould release, temporary protection, low surface energy |
| Tedlar® oriented / non-oriented | Orientation adapted according to the mechanical strength, elongation or formability required | According to grade | Deep drawing, texturing, aesthetic applications, complex surfaces |
Tedlar® product codes generally describe colour, thickness, surface treatment, gloss level and orientation. For example, a code TWH15BL3 corresponds to a white, nominal 38 µm film, low gloss, double-sided treated, type 3 oriented.
The values below correspond to the typical properties of DuPont™ Tedlar® PVF films. These must be validated according to the grade, thickness, surface treatment, and application specification.
Tedlar® films are used in applications where the surface needs to retain its properties when exposed to UV, solvents, moisture, cleaning agents, and external contamination.
Beyond distribution, ADDEV Materials transforms Tedlar® films to make them compatible with your production constraints: usable width, part format, adhesion level, laminated structure, and industrial packaging.
ADDEV Materials supports manufacturers looking for a reliable, available PVF Tedlar® film, processed into the correct format:
ADDEV Materials transforms technical films to deliver material directly usable on production lines, in rolls, sheets, cut parts, or kits.
Looking for Tedlar® film for an application exposed to UV, humidity, solvents, cleaning agents, or harsh outdoor environments? ADDEV Materials will help you define the right grade, treatment, and format for your process.
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.
