EAA hydrolytic aging
Sorun Belirtisi
EAA products in hot and humid environments show mechanical property decline >25%
Neden Analizi
EAA 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 grade with low polar group content 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 polar group sensitivity to water; selecting low polarity grade is key
