DSTDP fast UV aging
문제 현상
After 48h UV irradiation, DSTDP mechanical properties decrease >20%, yellowing
원인 분석
DSTDP molecular chains rapidly degrade by photo-oxidation under UV; surface molecular chains break forming microcracks
해결 방법
1) Add UV absorber 0.3-0.5wt% to block UV; 2) add HALS 0.2wt% for radical scavenging; 3) carbon black 2wt% to physically shield UV
핵심 요약
Fast UV aging is caused by photo-oxidation; UV absorber and HALS are key
