• Pelletized compound is extrusion-cast or calendared into films, which then undergo lamination with solar cells under vacuum/pressure and elevated temperature for controlled crosslinking and adhesion.

Final product types

• Packed PV encapsulation films, solar module back-sheets, and glass-laminated protection sheets for crystalline silicon solar panels.

5. Flexible Footwear Midsoles & Soling Sheets

Footwear compounders select this EVA grade for use in midsoles and soling sheets to provide lightweight cushioning, flexibility and chemical resistance. These properties meet the comfort and wear resistance demands in lifestyle, work safety, and athletic footwear, while ensuring uniform cell structure via foaming systems.
