    Processing
    Technology
  • Differentiation of Material Application of
    Materials with
    Long-term Reliability
  • Various Products Line Up High-functional
    Product Family
  • It is attached to the back of a solar cell module to prevent penetration of water, shock and UV rays, and protects the cell and module.
  • For long-term durability, film processing technology such as coating/lamination and coextrusion is applied by using fluoric film, weather-resistant PET, and weather-resistant polyolefin film.
