EEA Fast Thermal Aging

Problem Phenomenon

After aging at 80°C for 7 days, EEA product mechanical properties decline >30%

Cause Analysis

EEA molecular chains break and degrade under thermal oxidation; the antioxidant system is imperfect, protection insufficient

Solution

1) Improve the antioxidant system 1010+168+DSTDP; 2) Select high-molecular-weight grades; 3) Add 0.05wt% metal deactivator

Key Takeaway

Thermal aging is caused by thermal oxidation; improving the antioxidant system is key

EEA thermal aging thermal oxidation antioxidant high molecular weight
