PVDF film is safe, reliable, and has good corrosion resistance. It has become the preferred material for photovoltaic backsheet film, and its application in this field has been rapidly developed and widely recognized. Due to the global attention to the environment and the introduction of the fluorine restriction order, the development and application of PVDF's environmentally friendly alternative-fluorine-free glue is gradually advancing.

The fluorine-free glue developed by Jin Tianchi's team can replace PVDF in the photovoltaic backsheet mold after improvement. With its excellent weather resistance, the fluorine-free adhesive can effectively protect the PET base film in the middle layer of the back plate and improve the service life of the whole component.

Through relevant tests and tests, the performance advantages of the fluorine-free adhesive developed by our company in the application of photovoltaic back film are as follows:

1. Super weather resistance (UV resistance, heat and humidity resistance, UV DH resistance);

High temperature resistance (RTI≧ 125 ℃), low temperature toughness (-40 ℃);

3. High and low temperature cycle performance (TC600, using twisted welding belt);

4. Salt spray resistance.
