EEA Hydrolytic Aging
문제 현상
EEA product mechanical properties decline >25% in hot and humid environment
원인 분석
EEA 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 grades to reduce hydrolysis tendency; 2) Add anti-hydrolysis stabilizer; 3) Coat the product surface with a waterproof layer
핵심 요약
Hydrolytic aging is caused by the water sensitivity of polar groups; selecting low-polarity grades is key
