High silane content EVA copolymer adhesives for photovoltaic encapsulation film
COACE's main products are compatibilizers, tougheners and functional additives, which are used in: modified plastics, wood-plastic profiles, low-smoke halogen-free flame-retardant cables, PP extruded sheets, PE extruded sheets, and anti-corrosion pipes Coatings, hot melt adhesives, photovoltaic film additives and other fields, among which special products such as nylon ultra-low temperature toughener, polyester compatible toughener, alloy compatibilizer have reached the domestic advanced level.
R2120 is an EVA copolymer that has been functionalized with silane. This alteration gives R2120 distinct features such as a high silane content, high transparency, and low crystal point. High Silane Content EVA Copolymer Adhesives are designed to encapsulate photovoltaic (PV) modules. These innovative adhesives provide remarkable properties, benefits, and application adaptability. With their high silane concentration and specialised copolymer formulation, they offer a dependable bonding solution for PV module encapsulation, providing long-term durability and improved performance.
High Silane Content: The adhesives have a high concentration of silane, which facilitates strong adhesion between the encapsulant layers, which include Ethylene Vinyl Acetate (EVA) films and glass or backsheet materials. This ensures strong encapsulation integrity and resilience to environmental stresses.
Copolymer Formulation: The specialised copolymer composition improves the adhesive's mechanical strength, flexibility, and temperature resistance. This provides excellent module protection from temperature cycling, moisture intrusion, and possible delamination.
Optimal Rheological characteristics: The adhesives' rheological characteristics are accurately controlled, allowing for simple application throughout the lamination process. They provide proper flow and wetting characteristics, ensuring consistent covering and reducing air entrapment for increased module reliability.
UV Stability: The adhesives' high silane concentration improves their UV stability, avoiding yellowing and degradation from prolonged contact to sunshine. This ensures that the encapsulation film retains its optical clarity and performs efficiently over time.
Enhanced Module Durability: The high silane content and specialised copolymer composition provide superior adhesion, ensuring long-term encapsulation integrity and protection from environmental influences. This leads to better module durability and longer service life.
Improved Power Output: Because of the adhesives' exceptional adherence and optical transparency, light is transmitted to the PV cells more efficiently, resulting in a higher module power output. This leads to increased energy generation and better overall performance.
