POE flexural modulus low
Problem Phenomenon
POE product flexural modulus 20% below design value
Cause Analysis
POE soft, modulus low; filler addition insufficient or interface poor, no reinforcing effect; crystallinity low
Solution
1) Add 10-15wt% rigid filler to increase modulus; 2) Nucleating agent to increase crystallinity; 3) Select high modulus grade
Key Takeaway
Low flexural modulus is caused by soft material and insufficient filler; adding rigid filler is key
