THV Film
THV Film
ESONE’s THV (Tetrafluoroethylene-Hexafluoropropylene-Vinylidene fluoride) Fluorothermoplastic, a polymer made from tetrafluoroethylene, hexafluoropropylene, and vinylidene fluoride, offers unique advantages such as bonding capabilities with elastomers and hydrocarbon-based plastics, along with flexibility and optical clarity. ESONE THV films, produced via melt extrusion casting from THV resin, exhibit exceptional performance characteristics, including low processing temperatures and excellent flexibility. These films can be heat-sealed, thermoformed, and laminated to various substrates, making them ideal for multilayer hoses, tubes, sheets, and films.
Advantages of THV Foil
- Very high optical clarity and light transmission
- Outstanding flexibility compared to other fluoroplastics
- Good weatherability and UV stability
- Flame retardant and good dielectric properties
- Excellent chemical and permeation resistance
- Bondable to itself and other substrates for multilayer constructions
- Low processing temperatures for co-processing with olefinic plastics and hydrocarbon elastomers

Applications of THV Film
Clean POD devices in the semiconductor industry are made from advanced THV and ePTFE (modified Polytetrafluoroethylene) composites. These materials offer excellent chemical resistance, low permeability, and high thermal stability, making them ideal for protecting sensitive electronic components.
The combination enhances reliability and performance, ensuring effective sealing against contaminants. Customizable in various sizes, these composites meet diverse application needs within the semiconductor sector.
THV films are utilized in fuel and chemical tank linings, drop-in liners, and bag liners due to their exceptional chemical resistance to fuels across a wide temperature range and their low permeability to solvents and gases.
With excellent clarity (<1% haze) and outstanding mechanical and thermal properties, THV film is an ideal interlayer for lamination onto glass or for use between layers in multi-layer glass systems. It enhances fire safety and provides anti-shatter performance in various glass applications.
Thanks to their superior barrier properties, fire resistance, and high solar transmittance, THV films are well-suited for use as back sheets and front sheet glazing in photovoltaic (PV) panels.
