Products Description
RM211A is an anti-acidification additive for EVA amination. It is mainly used for EVA photovoltaic films to improve the aging resistance and anti-acidification properties of EVA films under high and gradually high humidity conditions.
EVA photovoltaic film anti-acidification additives enhance solar module longevity, dependability, and performance. These additives extend the lifespan and energy production of PV systems by reducing acid-induced deterioration and protecting against environmental conditions. The use of anti-acidification chemicals in the production process ensures that solar installations are long-lasting, cost-effective, and environmentally friendly. As the PV industry advances, these additives present a possible answer for solving acidity concerns, thereby contributing to the solar energy sector’s growth and sustainability.
Understanding Acidification of Photovoltaic Modules:
Acidification Causes: Acidification in PV modules is caused primarily by the penetration of moisture, oxygen, and contaminants through the encapsulant layer, resulting in the destruction of active components and decreased energy output.
Acidification Effects: Acid-induced corrosion can cause reduced module efficiency, delamination, discoloration, and even catastrophic failure, compromising solar modules’ overall performance and longevity.

- Composition and Function: EVA photovoltaic film anti-acidification additives are specially developed compounds that help to reduce acid-induced degradation in solar modules. These additives are frequently mixed into the ethylene-vinyl acetate (EVA) encapsulant layer during module manufacture.
- Chemical Properties: Anti-acidification additives have moisture resistance, oxygen barrier capabilities, and acid neutralisation properties, which assist protect the active components of PV modules from acid-induced corrosion.
- EVA Compatibility: Anti-acidification additives are designed to work with EVA encapsulants, ensuring seamless integration while maintaining the module’s mechanical and optical qualities.
Advantage
1.Acid Resistance: The fundamental advantage of EVA photovoltaic film anti-acidification additives is their capacity to improve PV modules’ acid resistance, protecting them from the negative effects of acidification.
2. Improved Reliability: By decreasing acid-induced corrosion, these additives help to improve module reliability, reduce performance deterioration, and extend the total life of solar panels.
3. Increased Energy output: Anti-acidification additives help to maintain the efficiency of PV modules, resulting in optimal energy output over a longer period.
4. Environmental Adaptability: Modules with anti-acidification additives are more resistant to a variety of environmental conditions, such as humidity, temperature fluctuations, and pollution exposure.
5. Cost-Effectiveness: By extending the lifespan and performance of PV modules, anti-acidification additives provide a cost-effective solution that reduces the need for premature module replacements while boosting the return on investment for solar projects.
