EEA Large Impact Strength Fluctuation
Problem Phenomenon
EEA product impact strength fluctuates ±30%, unstable
Cause Analysis
EEA dispersed phase particle size fluctuates 0.2-1μm, causing unstable toughening effect; crystallinity fluctuation affects impact
Solution
1) Stabilize processing conditions to ensure consistent dispersed phase particle size; 2) Nucleating agent to control crystallinity; 3) Raw material batch consistency control
Key Takeaway
Impact fluctuation is caused by unstable dispersed phase and crystallization; stable processing is key
