MADICO PV Backsheets PROTEKT TFB/PROTEKT TFB HD:

For Amorphous Silicon And Other Thin Film Solar Panels

MADICO Backsheets: PROTEKT TFB

Protekt Technology is a multi-layered laminate developed to construct a Leaner & Greener™ photovoltaic backsheet, which produces dramatically less unit mass and adheres to a lean manufacturing process. Protekt TFB uses a high performance film cast in a special process that when applied to the base Dielectric Bonding layers of PET/EVA results in a laminate with excellent stability characteristics for vacuum laminating processes and outdoor use. The new Protekt TFB uses a layer of Aluminum Foil which provides optimal barrier properties. The laminate is also available in custom colored EVA.

Advantages of Protekt TFB
• Optimal barrier properties
• No supply constraints
• Maximum bond strength to encapsulant
• Leaner & GreenerTM
• Ideal for thin film technologies

MADICO Backsheets: PROTEKT TFB-HD 

Protekt Technology is a multi-layered laminate developed to construct a Leaner & Greener™ photovoltaic backsheet, which produces dramatically less unit mass and adheres to a lean manufacturing process. Protekt TFB HD uses a high performance film cast in a special process that, when applied to the base Dielectric Bonding layers of PET/EVA, results in a laminate with excellent stability characteristics for vacuum laminating processes and outdoor use. The new Protekt TFB HD uses a layer of Aluminum Foil which provides optimal barrier properties. The “HD” version uses thicker PET and meets IEC 60664 1000 VDC. The laminate is also available in custom colored EVA.

Advantages of Protekt TFB HD
• Optimal barrier properties
• No supply constraints
• Maximum bond strength to encapsulant
• Leaner & GreenerTM
• Ideal for thin film technologies

MADICO Backsheets: TAPE

TAPE is a multi-layered film lamination designed to be used as a backing sheet for photovoltaic solar panels. It acts as a durable protective barrier for panel shaped electronic devices that undergo heat and vacuum lamination. The TAPE construction provides exterior durable performance, optimal dielectric properties and adhesion with aluminum for excellent vapor barrier benefits while providing good dielectric strength.

Advantages of TAPE
• Proven PVF performance
• Ultimate moisture barrier
• Ideal for thin film technologies
• Increased bond strength
• Improved aesthetic appearance
• Width capabilities up to 72 inches
