DSTDP low elongation at break
Problem Phenomenon
DSTDP product elongation at break <100%, below the 200% requirement
Cause Analysis
DSTDP molecular weight on the low side, chains short, entanglement insufficient; excessive orientation, transverse elongation extremely low; excessive crosslinking restricting chain slippage
Solution
1) Select high molecular weight DSTDP to increase entanglement density; 2) reduce orientation, lower injection speed; 3) control crosslinking degree to avoid excess
Key Takeaway
Low elongation at break is caused by low molecular weight and orientation; selecting high MW and reducing orientation are key
