POE tensile strength insufficient
Problem Phenomenon
POE product tensile strength 15-20% below standard value
Cause Analysis
POE molecular weight low, strength foundation insufficient; filler interface poor, no reinforcing effect; excessive orientation, longitudinal strong and transverse weak
Solution
1) Select high molecular weight POE grade; 2) Filler coupling agent treatment to improve interface; 3) Reduce orientation to reduce longitudinal-transverse difference
Key Takeaway
Insufficient tensile strength is caused by molecular weight and poor interface; selecting high MW grade is key
