DSTDP hydrolysis aging
Fenómeno do problema
DSTDP product mechanical properties decrease >25% in hot and humid environment
Análise das causas
DSTDP contains polar groups, hydrolyzed and chain broken under hot and humid conditions; ester bonds/amide bonds etc. are water sensitive
Solução
1) Select grades with low polar group content to reduce hydrolysis tendency; 2) add anti-hydrolysis stabilizer; 3) coat the product surface with a waterproof layer
Conclusão principal
Hydrolysis aging is caused by polar groups being water sensitive; selecting low-polarity grades is key
