Backsheet

한화첨단소재의 Backsheet는 완벽한 전기 절연성과 우수한 내구성으로 태양광 모듈의 효율을 최고로 유지합니다.

제품정보

  • 다양한 필름 가공 기술 보유
  • 소재 차별화 장기신뢰성 소재 적용
  • 다양한 제품 Line Up 고기능성 제품군 보유

태양전지 모듈 배면에 부착되어 다양한 외부 환경(수분, 충격, UV)으로 부터 Cell 및 모듈을 보호하는 시트입니다.

장기 내구성을 위해 불소계 필름 및 내후성 PET, 내후성 폴리올레핀 필름을 사용하여 Coating/Lamination 및 공압출 등 필름가공 기술이 적용된 제품입니다.
