Mylar® and Melinex® polyester films
DuPont Teijin Films offers module manufacturers a number of value adding films that provide cost effective back sheet solutions.
Mylar® and Melinex® PET films are designed to provide excellent hydrolysis, dielectric, interlayer laminate adhesion, reflectance, UV protection and durability properties in back sheet laminations.
These PET films are custom manufactured in Europe for back sheet laminators who supply module makers using c-Si to emerging flexible thin film, roll to roll, technologies.
Commonly selected films include:
The traditional back sheet design for c-Si PV modules is a laminate of Mylar® PET polyester film between two layers of DuPont™ Tedlar® PVF Films, known as a TPT™ laminate.
New, 100% polyester film laminate designs use 2 or 3 layers of Melinex® polyester films.
Further Enhanced Film Offerings
Teonex® PEN and Melinex® ST™ polyester films provide high temperature dimensional stability. Teonex® PEN will also provide improved barrier and UV protection over standard PET films.
