Injection Molding

POE toughened PP flowability greatly reduced
Problem Phenomenon
POE/PP MFR drops from 15 to 3-5, injection short shot
Cause Analysis
POE molecular weight high and viscosity large, adding 15-20wt% viscosity rises significantly
Solution
1) Low viscosity POE MFR>5; 2) Temperature 185-200°C; 3) Oxidized PE wax 0.3-0.5wt%; 4) POE+talc synergy
Key Takeaway
Flowability reduction can be balanced with low-viscosity grades and processing aids
