UV Absorber and Antioxidant 168 for EVA Solar Encapsulation Film: EcoChem Supports Indian Solar Film Customers
Recently, EcoChem received an inquiry from an Indian customer looking for additives used in EVA solar encapsulation film. The customer wrote:
“We are interested in UV absorber for EVA solar encapsulation film, we are interested in antioxidant 168 grade, can you offer? Please share the TDS.”
This inquiry is very typical in the photovoltaic materials market. As solar module production continues to grow in India and other countries, manufacturers of EVA solar encapsulation film are paying more attention to the long-term stability, transparency, processing performance, and weather resistance of their film products. To meet these requirements, high-quality polymer additives such as UV absorbers and antioxidants are essential.
For customers who produce EVA encapsulation film, the right additive system can help reduce yellowing, improve processing stability, slow polymer degradation, and support the long service life of photovoltaic modules. EcoChem, as a polymer additives supplier in China, can provide UV absorbers, Antioxidant 168, and related stabilization solutions for EVA film and other plastic applications.
What Is EVA Solar Encapsulation Film?
EVA, or ethylene-vinyl acetate, is widely used as an encapsulation material in photovoltaic modules. In a solar module, EVA film is placed between the glass, solar cells, and backsheet. After lamination, it helps bond the different layers together and protects the solar cells from moisture, dust, oxygen, heat, and mechanical stress.
Because photovoltaic modules are used outdoors for many years, EVA encapsulation film must maintain good transparency, adhesion, flexibility, and durability under harsh environmental conditions. Long-term exposure to sunlight, ultraviolet radiation, oxygen, and high temperature may cause polymer degradation. This can lead to yellowing, reduced light transmission, loss of mechanical properties, and lower module performance.
That is why additives such as UV absorbers and antioxidants are important in EVA solar film formulations.
Why EVA Solar Encapsulation Film Needs UV Absorber
UV radiation is one of the main causes of polymer aging. When EVA film is exposed to sunlight for a long period, ultraviolet light may break down the polymer chain and accelerate oxidation. This process may result in color change, yellowing, haze increase, and performance loss.
A suitable UV absorber for EVA solar encapsulation film can absorb harmful UV light and convert it into less harmful energy. This helps protect the EVA resin and improve the outdoor durability of the film.
For solar encapsulation film, a UV absorber should have several important properties. It should have good compatibility with EVA resin, strong UV absorption ability, low volatility, good thermal stability, and minimal influence on film transparency. Since the film is used in photovoltaic modules, optical performance is especially important. The additive should not significantly reduce light transmission or create haze problems.
EcoChem can support customers in selecting suitable UV absorber grades according to their EVA film formulation, processing conditions, and performance requirements.
Antioxidant 168 for EVA Film Processing
In the customer’s inquiry, Antioxidant 168 was also mentioned. Antioxidant 168 is a widely used phosphite antioxidant in plastics and polymer processing. It is commonly used as a secondary antioxidant to improve processing stability and reduce polymer degradation during high-temperature processing.
During EVA film extrusion, compounding, and lamination, the material is exposed to heat and oxygen. Without proper stabilization, oxidation may occur. This can cause discoloration, molecular weight change, processing instability, gel formation, or reduced product quality.
Antioxidant 168 helps decompose hydroperoxides formed during oxidation. It is often used together with primary antioxidants and light stabilizers to build a complete stabilization system. In EVA solar encapsulation film, Antioxidant 168 can help improve processing performance and reduce thermal oxidative degradation.
For customers in the solar encapsulation film industry, Antioxidant 168 is not only a processing aid but also part of the long-term stability strategy of the final film product.
Why UV Absorber and Antioxidant 168 Are Often Used Together
EVA solar film is exposed to multiple aging factors at the same time. UV light, oxygen, heat, and moisture may all affect the performance of the film. A single additive may not be enough to provide complete protection. Therefore, film manufacturers often use a combined stabilization system.
UV absorbers mainly protect the polymer from ultraviolet radiation. Antioxidants mainly protect the polymer from oxidative degradation during processing and service life. When used together in a suitable formulation, they can help improve color stability, thermal stability, processing safety, and outdoor durability.
For EVA solar encapsulation film, the additive package may include UV absorber, primary antioxidant, secondary antioxidant such as Antioxidant 168, and sometimes other light stabilizers. The exact formulation depends on the customer’s film structure, production process, lamination temperature, target performance, and cost requirements.
EcoChem can provide product information and technical discussion to help customers evaluate different additive options.
Key Requirements for Additives Used in EVA Solar Encapsulation Film
Solar encapsulation film is a high-performance application. Compared with general plastic products, it has stricter requirements for additives. When choosing a UV absorber or antioxidant for EVA solar film, customers usually consider the following factors.
First, thermal stability is very important. EVA film production involves heat processing, so the additive should be stable under processing temperatures. If the additive decomposes too easily, it may cause color change or performance problems.
Second, compatibility with EVA resin is essential. Poor compatibility may lead to migration, blooming, uneven dispersion, or surface defects. These issues can negatively affect film quality and module reliability.
Third, optical performance must be carefully controlled. Solar encapsulation film needs high transparency and low haze. Additives should not significantly reduce light transmission.
Fourth, long-term weather resistance is required. Photovoltaic modules are expected to work outdoors for many years. Additives should help the film resist UV, heat, oxygen, and humidity.
Fifth, product consistency matters. Solar film manufacturers need stable quality from batch to batch. A reliable supplier should provide consistent product specifications, TDS, COA, and professional communication.
