Industrial Applications

Tedlar® PVF protective film provides a variety of applications in Industrial usage


Explore new opportunities and growth with innovation

Made of 100% fluororesin PVF, Tedlar® has introduced new dimensions of surface protection, security and safety in a wide variety of applications. We encourage our customers to develop new ideas for Tedlar®, and to dream big.

  • DuPont™ Tedlar® high temperature and chemical resistant properties make it ideal for use in high voltage electrical power applications.

    Release Films

    The properties of DuPont™ Tedlar® release film make it ideal for use in the curing process of demanding high voltage electrical power applications. These include large turbine generators used in winding/stator insulation with epoxy-mica and epoxy-glass compounds.

    Tedlar® release films are designed to contain resins during the autoclave curing process and have excellent anti-stick properties for both epoxy-blend insulations and high temperature autoclave fluids, which facilitate removal. 

    Protective Films

    Tedlar® is also used as a protective overwrap in large conductor insulation systems such as those used in downhole cables and oil-well power cables. It is ideal for these applications because of its excellent high temperature capability combined with chemical resistance in harsh environments. 

  • DuPont™ Tedlar® release films help provide an ideal release for fiber-reinforced polymer (FRP) and carbon-fiber-reinforced polymer (CFRP) composites.

    With Tedlar® release films, the molds of parts and linings are protected and have ability to stay in place during curing and processing under temperature and pressure.

    Reduce manufacturing costs

    Tedlar® release films help reduce manufacturing costs in multiple ways. With an excellent release from resin systems, the need for wet-applied release additional agents is eliminated. Also, with a matte finish and a high level of surface quality, manufacturing steps, such as sanding, are eliminated and rejection and re-work rates are greatly reduced.

    Tedlar® release films also have the strength and formability to reduce finishing times and surface defects.

    Typical applications include:

    • Wind turbines
    • Windmill blades
    • Aviation parts
    • Computers
    • Electronics
  • DuPont™ Tedlar® PVF films are used in the production of wind turbine blades as both a release film and a protective surface. As a protective surface Tedlar® has the ability to resist weathering, moisture and UV rays, while also offering low drag to effectively keep surfaces clean. Tedlar® has demonstrated exceptional performance in marine/salt water environments.

    As a Protective Surface

    • Long-term durability
    • Good abrasion resistance
    • Excellent chemical and corrosion resistance
    • Resistant to dirt accumulation and easy to clean

    As a Release Film

    • Excellent in release for thermoset blade manufacturing
    • Clean release – no transfer of release material for fast finishing
    • Temperature resistance to 180 °C cure cycles
    • Good tensile strength for fast, complete peel
    • 3-D conformability

    Typical Applications

    • Wind turbine blades – release and protective films
    • Towers – protective films
    • Nacelles – protective films
  • DuPont™ Tedlar® release films are ideal for transfer printing because they offer excellent printability and release cleanly from rubber and metal tubing during steam curing of rubber hoses and fan belts.

    Tedlar® films can retain toughness through aggressive cycles, and offer excellent thermal stability to resist embrittlement and degradation at processing temperatures up to 185°C (365°).

    For many companies, Tedlar® films have become the material of choice over triacetate and other materials because of their ability to withstand moisture and higher temperatures.

    Tedlar® films are available in all popular transfer printing sizes, including nominal thicknesses of 1 mil, 1.5 mil and 2.0 mil and widths up to 72 in.

  • Tedlar® outperforms competition with optimal balance of high temperature capability, conformability, toughness and release from adhesives for PCB lamination – contains no silicone.

    DuPont™ Tedlar® release films provide outstanding release from acrylics, phenolics and epoxies used in the PCB industry. Tedlar® films have excellent balance, high temperature capability, conformability, toughness and release from bonding adhesives. Its excellent conformability ensures uniform pressure and controlled squeeze out in vias.

    In the PCB industry, many users want to increase their press temperatures to reduce their production cycle in order to increase output. Tedlar® has been demonstrated to outperform many of the current release films used in this application, allowing the users to postpone expensive capital investment for new press capacity. In addition Tedlar® contains no silicone thus alleviating industry concern for potential migration to other substrates that come in contact with the release film which could cause downstream processing and end use issues.  

  • Tedlar® release films offer gas permeation resistance into and out of the sample bags, assuring sample integrity.

    Tedlar® release films offer gas permeation resistance into and out of the sample bags, assuring sample integrity. Because Tedlar® is chemically inert, it will not react with or alter the composition of the wide range of collected chemicals in your sample. Teldar® film has been the industry gold standard for years due to superior inertness, impermeability and abrasion resistance.

    Gas sampling bags made of Tedlar® PVF film are recommended in many US EPA methods including TCLP and methods TO-3 (VOCs), TO-12 (NMOC), TO-14A (VOCs), TO-15 (VOCs), ASTM D-5504 (reduced sulfur compounds) and a variety of atmospheric gas methods. Tedlar® release films are rated for continuous use from -72°C to 107°C (-98°F to 225°F).
