DSTDP fast thermal aging
Problembeschreibung
DSTDP product mechanical properties decrease >30% after aging at 80°C for 7 days
Ursachenanalyse
DSTDP molecular chains break and degrade under thermo-oxidation; antioxidant system incomplete, protection insufficient
Lösung
1) Complete antioxidant system 1010+168+DSTDP; 2) select high molecular weight grades; 3) add metal deactivator 0.05wt%
Wichtigste Erkenntnis
Thermal aging is caused by thermo-oxidation; completing the antioxidant system is key
