Low EAA flexural modulus
Problem Phenomenon
EAA product flexural modulus <20% of design value
Cause Analysis
EAA is soft with low modulus; insufficient filler addition or poor interface not providing reinforcement; crystallinity too low
Solution
1) Add 10-15wt% rigid filler to increase modulus; 2) Use nucleating agent to increase crystallinity; 3) Select high modulus grade
Key Takeaway
Low flexural modulus is caused by material softness and insufficient filler; adding rigid filler is key
