Solar Materials

Encapsulant

Encapsulant of Hanwha Advanced Materials has excellent quality with Calender and T-Die method.

Product Info.

  • Facility to Supply Products according to Customer Needs Calendering & T-Die
  • World-class Productivity
  • Various Products Line UpHigh-functional Product Family

It is a sheet which is used for adhesion of Glass/Cell/Backsheet of solar cell modules and for cell protection (encapsulant), and which requires long-term durability (more than 25 years) and optical characteristics. Hanwha Advanced Materials supply high quality raw materials based on Hanwha Group's global competitiveness in the EVA raw material market for solar cells. Our EVA sheets have been recognized for its superior quality all over the world by applying the highly-regarded calendar process and T-die method.
