EVA film is a type of high-viscosity film material composed of high-molecular resin (ethylene vinyl acetate copolymer), added with special additives, and processed using specialised machinery. It is also known as modified EVA material for laminated glass.It adheres firmly to artificial glass.
It has the qualities of toughness, transparency, temperature resistance, cold resistance, high adhesion strength, high elongation at break, and excellent humidity resistance. The production of safety laminated glass around the globe uses it as an ideal and affordable adhesion material. Additionally, it can partly replace PVB materials used in the construction and automotive industries.
The Global Electric vehicle EVA encapsulation film market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Ethylene vinyl acetate (EVA) copolymer has predominated as the encapsulating material in the majority of these research, despite the fact that different kinds of encapsulation methods have been developed thus far. The power production efficiency of the PV module is reduced as a consequence of the ease with which EVA is susceptible to environmental-related degradation.
As a result, the research community has given serious consideration to investigating novel methods for improving the EVA encapsulate film’s ability to resist ageing. These methods include extending the cross-linking network structure in the polymer matrix and combining antioxidants, UV absorbers, and photo stabilisers.
The designing approaches for polymer encapsulates, however, were significantly impacted by advancements in the area of polymers over time.With regard to gas and moisture permeability, polymer composites reinforced with carbon and inorganic fillers work very well as barriers.
These polymer composites can be used as the encasing parts of electrical devices to shield them from damaging environmental effects. In response to UV or sunlight, photo-responsive polymers are a type of smart polymers.
Photo-responsive polymers are used in a variety of electronic applications, including adhesion, sealing, potting, gasketing, and encapsulating, due to their quick curing and ability to create a cross-linking network structure when exposed to light.
Researchers worked diligently to create novel and sophisticated polymer encapsulates with greater operational longevity, spurred on by these high-performance polymers.
