DuPont™ Teflon® film is a substitute for glass in the lamination process to produce flexible photovoltaic systems. Teflon®, which is used as the top layer of the module, brings a very high level of light transmittance in the operating wavelength range of the solar cells. It is lighter and less fragile than glass and shows very little degradation over a long period of time. It also offers excellent mechanical strength and reliability.

DuPont Teflon® film is often used to make small, unbreakable solar panels that can be combined with electronic components to provide roof mounted ventilation systems for motor coaches, mobile shops, trucks, ambulances and fire engines. In fixed applications, they can be fitted to security posts, conservatories, warehouses and other types of buildings.

Reasons for Choosing Teflon® 1. Lighter and less fragile than glass
2. High level of light transmittance
3. Little degradation over long periods of time
4. Excellent mechanical strength
5. Extremely flexible

Films of Teflon® – Fluoropolymer Resin Teflon® films feature outstanding ultra-violet stability because they are UV transparent. The films’ very low surface energy means that they are slow to get dirty, and easy to clean, if necessary. Teflon® films are rugged and clear thermoplastics that combine superior mechanical strength and toughness with excellent chemical resistance and dielectric properties. They have good cut-through resistance, tear strength, and excellent weathering performance.

Teflon® Attributes

• Tough and strong
• Available as heat stabilized or heat shrinkable
• Resist temperature extremes and chemicals and solvents
• Excellent electrical insulation properties
