EMA hydrolysis aging

문제 현상

EMA product mechanical properties decline >25% in hot and humid environment

원인 분석

EMA contains polar groups that hydrolyze and break chains under hot and humid conditions; ester bonds/amide bonds etc. are sensitive to water

해결 방법

1) Select low polarity content grade to reduce hydrolysis tendency; 2) Add anti-hydrolysis stabilizer; 3) Coat product surface with waterproof layer

핵심 요약

Hydrolysis aging is caused by polar groups being sensitive to water; selecting low polarity grade is key

EMA hydrolysis aging polar groups anti-hydrolysis stabilizer waterproof coating
