EMA hydrolysis aging
Sorun Belirtisi
EMA product mechanical properties decline >25% in hot and humid environment
Neden Analizi
EMA 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 grade to reduce hydrolysis tendency; 2) Add anti-hydrolysis stabilizer; 3) Coat product surface with waterproof layer
Temel Çıkarım
Hydrolysis aging is caused by polar groups being sensitive to water; selecting low polarity grade is key
