Poor EVOH Chemical Resistance
Sorun Belirtisi
EVOH products soaked in acid/alkali solvents show mechanical decline >30%
Neden Analizi
EVOH has high affinity for specific chemicals, being attacked and swollen; EVOH molecular chains attacked by chemicals and broken
Çözüm
1) Select chemical-resistant grade; 2) Slight crosslinking to reduce swelling; 3) Product surface coating protection; 4) Add chemical stabilizer
Temel Çıkarım
Poor chemical resistance is caused by EVOH chemical affinity; selecting chemical-resistant grade and coating are key
