Mylar®, Melinex® and Teijin®Tetoron® polyester films
The world’s leading supplier of polyester (PET) films, DuPont Teijin Films™ offers backsheet laminators and module manufacturers a number of value adding films that provide cost effective backsheet solutions with 3rd party lab certification and backed by a 50+ year reputation for innovation, quality and performance.
Mylar®, Melinex® and Teijin®Tetoron® PET films are designed to provide excellent hydrolysis, dielectric, reflectance, UV protection and durability properties in backsheet laminations.
These PET films are custom manufactured in Europe, US, Japan and China for laminators who supply module makers producing c-Si to emerging flexible thin film modules using roll to roll technology.
The traditional backsheet design for c-Si PV modules is a laminate of Mylar® PET polyester film between two layers of DuPont™ Tedlar® PVF film, commonly referred to as a TPT™ laminate.
New, 100% polyester film laminate designs use 2 to 3 layers of Melinex® polyester film.
