Fast EMA thermal aging
Problembeschreibung
After aging EMA products at 80°C for 7 days, mechanical properties decline >30%
Ursachenanalyse
EMA molecular chains break and degrade under thermo-oxidation; antioxidant system incomplete with insufficient protection
Lösung
1) Complete the antioxidant system 1010+168+DSTDP; 2) Select high molecular weight grade; 3) Add metal deactivator 0.05wt%
Wichtigste Erkenntnis
Thermal aging is caused by thermo-oxidation; completing the antioxidant system is key
