DSTDP poor fatigue resistance
Problem Phenomenon
DSTDP product fatigue life <10⁴ cycles, below the 10⁵ cycles requirement
Cause Analysis
DSTDP elastic recovery insufficient, plastic deformation accumulates each cycle; crosslinking degree on the low side, fatigue crack propagation fast
Solution
1) Increase crosslinking degree to improve recovery and reduce accumulated deformation; 2) select high molecular weight grades to raise the fatigue threshold; 3) product design to reduce stress concentration
Key Takeaway
Poor fatigue resistance is caused by insufficient recovery and fast crack propagation; increasing crosslinking is key
