CEF chemical resistance poor
Problembeschreibung
After the CEF product is immersed in acid, alkali and solvent, the mechanical properties decrease by >30%
Ursachenanalyse
CEF has a high affinity for specific chemicals and is eroded and swollen; the CEF molecular chain is attacked and broken by chemicals
Lösung
1) Select chemically resistant grades; 2) Slight crosslinking to reduce swelling; 3) Coating protection on the product surface; 4) Add chemical stabilizers
Wichtigste Erkenntnis
Poor chemical resistance is caused by the chemical affinity of CEF; selecting chemically resistant grades and coatings is the key
