EEA Hydrolytic Aging
Sorun Belirtisi
EEA product mechanical properties decline >25% in hot and humid environment
Neden Analizi
EEA contains polar groups that hydrolyze and break chains under hot and humid conditions; ester bonds/amide bonds etc. are sensitive to water
Çözüm
1) Select low-polarity-content grades to reduce hydrolysis tendency; 2) Add anti-hydrolysis stabilizer; 3) Coat the product surface with a waterproof layer
Temel Çıkarım
Hydrolytic aging is caused by the water sensitivity of polar groups; selecting low-polarity grades is key
