EEA Poor Chemical Resistance

Problembeschreibung

After immersion in acid/alkali solvents, EEA product mechanical properties decline >30%

Ursachenanalyse

EEA has high affinity for specific chemicals, being eroded and swollen; EEA molecular chains are attacked by chemicals and broken

Lösung

1) Select chemical-resistant grades; 2) Slight crosslinking to reduce swelling; 3) Product surface coating protection; 4) Add chemical stabilizers

Wichtigste Erkenntnis

Poor chemical resistance is caused by EEA chemical affinity; selecting chemical-resistant grades and coating are key

EEA chemical resistance chemical attack slight crosslinking surface coating
