Poor EMA chemical resistance

문제 현상

After soaking EMA products in acid, alkali or solvent, mechanical properties decline >30%

원인 분석

EMA has high affinity for specific chemicals and is attacked and swelled; EMA molecular chains attacked by chemicals and broken

해결 방법

1) Select chemical resistant grade; 2) Slight crosslinking to reduce swelling; 3) Product surface coating protection; 4) Add chemical stabilizer

핵심 요약

Poor chemical resistance is caused by EMA chemical affinity; selecting chemical resistant grade and coating are key
