EEA Poor Chemical Resistance
Fenómeno do problema
After immersion in acid/alkali solvents, EEA product mechanical properties decline >30%
Análise das causas
EEA has high affinity for specific chemicals, being eroded and swollen; EEA molecular chains are attacked by chemicals and broken
Solução
1) Select chemical-resistant grades; 2) Slight crosslinking to reduce swelling; 3) Product surface coating protection; 4) Add chemical stabilizers
Conclusão principal
Poor chemical resistance is caused by EEA chemical affinity; selecting chemical-resistant grades and coating are key
