MP Hydrolytic Aging
ظاهرة المشكلة
Mechanical properties of MP products decrease >25% in hot and humid environments
تحليل الأسباب
MP contains polar groups that hydrolyze and break chains under hot and humid conditions; ester bonds/amide bonds etc. are sensitive to water
الحل
1) Select grades with low polar group content to reduce hydrolysis tendency; 2) Add anti-hydrolysis stabilizers; 3) Coat the product surface with a waterproof layer
الخلاصة الأساسية
Hydrolytic aging is caused by the water sensitivity of polar groups; selecting low-polarity grades is key
