Demand for polyvinylidene fluoride (PVDF) and polyvinyl fluoride (PVF) will grow at the fastest rates through 2019.
JinkoSolar said this strategic collaboration will reportedly focus on the technical development efforts to support continued improvements in the efficiency, durability and reliability of solar cells and panels as well as the development and supply of advanced materials including DuPont Solamet PV19x series photovoltaic metallization pastes and DuPont Tedlar polyvinyl fluoride films.
However, the most robust gains are forecast for polyvinyl fluoride (PVF) and polyvinylidene fluoride (PVDF).
The company says that they offer "excellent adhesion to several back-sheet materials such as polyvinyl fluoride (PVF) and polyethylene terephthalate (PET) and also adhere to junction box materials such as polyphenylene oxide (PPO) and polycarbonate.
For example, DuPont Tedlar polyvinyl fluoride (PVF) film, used as a component of the photovoltaic backsheet, is a key material that protects the PlanetSolar modules and ensures reliable power generation during the cruise.
For example, DuPontEoAaAo TedlarEeA polyvinyl fluoride (PVF) film, used as a component of the photovoltaic backsheet, is a key material that protects the PlanetSolar modules and ensures reliable power generation during the cruise.
Chemical inertness, dimensional stability (which helps ensure manufacturing compatibility), and strong mechanical properties with regard to strength, durability, and crack resistance all play a part in the utility of polyvinyl fluoride film.
