CEF thermal aging fast
Problem Phenomenon
After aging at 80°C for 7 days, the mechanical properties of the CEF product decrease by >30%
Cause Analysis
The CEF molecular chain breaks and degrades under thermal oxidation; the antioxidant system is incomplete and the protection is insufficient
Solution
1) Improve the antioxidant system 1010+168+DSTDP; 2) Select high-molecular-weight grades; 3) Add metal deactivator 0.05wt%
Key Takeaway
Thermal aging is caused by thermal oxidation; improving the antioxidant system is the key
