CEF impact strength fluctuation large
Problem Phenomenon
The impact strength of the CEF product fluctuates ±30%, unstable
Cause Analysis
The CEF dispersed phase particle size fluctuates 0.2-1μm, resulting in unstable toughening effect; crystallinity fluctuations affect the impact
Solution
1) Stabilize the processing conditions to ensure consistent dispersed phase particle size; 2) Nucleating agent to control the crystallinity; 3) Control the batch consistency of raw materials
Key Takeaway
Impact fluctuation is caused by unstable dispersed phase and crystallization; stabilizing the processing is the key
