CEF hydrolysis aging
문제 현상
The mechanical properties of the CEF product decrease by >25% in a humid and hot environment
원인 분석
CEF contains polar groups that hydrolyze and break the chain under humid and hot conditions; ester bonds/amide bonds, etc. are sensitive to water
해결 방법
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
핵심 요약
Hydrolysis aging is caused by the sensitivity of polar groups to water; selecting low-polarity grades is the key
