POE and PA blend incompatible
Problem Phenomenon
POE/PA mechanical properties lower than pure components, impact completely delaminated
Cause Analysis
POE polyolefin and PA polyamide have large polarity difference, completely incompatible
Solution
1) POE-g-MAH 2-5wt%; 2) ADR-4468 1-2wt%; 3) PA end groups bonded with MAH; 4) High shear POE<0.3μm
Key Takeaway
POE/PA incompatibility requires POE-g-MAH chemical bonding to solve
