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