Beschreibung
Zusammenfassung:	The present invention relates to an ethylene vinyl acetate copolymer composition for a solar cell encapsulant. More specifically, the ethylene vinyl acetate copolymer composition secures heat resistance without a loss to solar transmittance of anhydrous ternary hydrotalcite-based hydroxyl ethylene vinyl acetate copolymer, is effective for long-term physical properties, suppresses corrosion of glass by removing acetic acid, and exhibits anti PID performance effectively by preventing sodium (Na) ions from being generated. 본 발명은 태양전지 봉지재용 에틸렌 비닐아세테이트 공중합체 조성물에 관한 것으로, 보다 상세하게는 무수 삼원계 하이드로탈사이트계 수산제에틸렌 비닐아세테이트 공중합체 태양광 투과율에 손실을 가하지 않으면서 내열성이 확보되어 장기 물성에 효과적이며 초산을 제거하여 유리의 부식을 억제하고 Na 이온의 생성을 억제하여 효과적으로 anti PID 성능을 발휘할 수 있다.
