- Inorganic Additives: The masterbatch contains inorganic additives that give EVA films outstanding acid resistance qualities. These additives are incorporated into the manufacturing process. The integrity of the film as well as its performance are both maintained thanks to these additives, which create a barrier that protects against acid attacks.
- Easy Dispersibility: The masterbatch has been specifically designed to provide easy dispersion inside the EVA matrix throughout the process of film making through its own unique engineering. The film’s acid resistance capabilities are improved throughout the entire film as a result of its one-of-a-kind formulation, which guarantees a uniform distribution of the inorganic additives.
- Ethylene-Vinyl Acetate Copolymer Base: The masterbatch is based on an ethylene-vinyl acetate copolymer, which ensures compatibility and excellent dispersion inside the EVA matrix. This is the basis for the masterbatch. These compatibilities contribute to the overall performance and stability of the EVA film, which is a positive aspect.
- Environmental Compatibility: The inorganic composition of the masterbatch guarantees that it is completely compatible with the environment, which makes it an environmentally responsible option for photovoltaic applications.
Advantage
a. Enhanced Acid Resistance: The masterbatch makes a significant improvement to the acid resistance of EVA films, which protects them from the deterioration that is induced by exposure to acid. This not only extends the lifespan of the film but also ensures that its performance is maintained even in difficult settings.
b. Improved Dispersion: The easiness with which the masterbatch may be dispersed guarantees that the inorganic additions are distributed evenly throughout the EVA matrix. As a result, the film’s acid resistance capabilities remain consistent throughout its entirety, which contributes to an improvement in its overall performance and reliability.
c. The masterbatch helps to retain the mechanical and electrical properties of EVA films for an extended period of time by providing better acid resistance. This is referred to as the extended service life. Because of this, the film’s service life is increased, which guarantees its continued performance and dependability over time.
d. Versatile Application: The masterbatch, which is simple to disperse, is suited for a wide range of applications that involve EVA films. These applications include backsheets, encapsulants, and other protective layers. It can be easily included into the manufacturing procedures that are already in place, which will result in an increase in the acid resistance of the film without sacrificing any of the other features of the film.
