DuPont Teijin Films, the world’s leading manufacturer of PET polyester films, offers a range of films tailored to the photovoltaic market.
In existing technologies the most popular backsheet construction is a “sandwich” of Mylar® PET polyester film between two layers of DuPontTM Tedlar®.
This trilaminate is commonly referred to as T/P/T. Mylar® polyester film is the ideal candidate for the TPT laminate because of its properties:
- Excellent electrical properties
- Meets water vapour barrier requirements
- Has tailored dimensional stability
- Is easy to handle
- Robust “cut-through” and tear resistance
Mylar® PET polyester films for this application area are available in a range of thicknesses from 50 microns (2 mil) up to 250 microns (10 mil), with other thicknesses possible by discussion.
