Descrizione dei prodotti
One kind of silane-functionalized ethylene-vinyl acetate (EVA) copolymer is called R2120. R2120 now has special qualities due to this alteration, such as a high silane content, great transparency, and a low crystal point.
The use of EVA graft silane copolymer additives, which provide noteworthy benefits such increased adhesion, mechanical strength, UV resistance, and moisture barrier qualities, is crucial for photovoltaic encapsulation. These additives support maximum energy conversion efficiency and lower maintenance costs by extending the overall lifespan, durability, and dependability of PV modules. The rise and adoption of solar energy as a sustainable and renewable power source is supported by the use of EVA graft silane copolymer additives in PV module manufacturing processes, which guarantee the creation of high-quality modules appropriate for a variety of applications in the solar PV industry.

Good silane concentration, good transparency, and low crystal point characterize the silane functionalized ethylene-vinyl acetate copolymer.
- Reactive Silane Coupling Agents: The reactive silane coupling agents included in the EVA graft silane copolymer additives help to improve the interfacial compatibility and adhesion strength by promoting covalent bonding between the EVA copolymer and other components like the glass or backsheet.
- Enhanced Cross-Linking: By encouraging cross-linking reactions inside the EVA copolymer matrix, these additives improve the material’s resilience to environmental influences, mechanical strength, and thermal stability.
- UV-Resistance: The encapsulating material’s resistance to UV degradation is improved by the addition of UV-stabilizing components to the additives, assuring long-term dependability and preserving optical transparency.
- Moisture Barrier Properties: By improving the encapsulating material’s moisture barrier qualities, EVA graft silane copolymer additives lower the chance of delamination and raise overall module dependability.
Vantaggio
Good Compatibility: The graft silane copolymer additives are easily incorporated into the current encapsulation methods due to their great compatibility with EVA copolymers.
Optimal Dispersion: By providing greater dispersibility in the EVA matrix, these additives guarantee even distribution and enhanced mechanical qualities across the encapsulation film.
Low Yellowing: The additives provide low yellowing properties that help to maintain the encapsulating material’s look and optical clarity over time.
The EVA graft silane copolymer additives exhibit exceptional thermal stability, enabling them to function even at elevated operating temperatures.
Enhanced Module Reliability: By strengthening the bonds between various components, these additives lower the chance of delamination and increase the overall dependability of PV modules.
