POE/glass fiber '2079851475616104452 floating fiber
Problem Phenomenon
POE/20wt% glass fiber, surface exposed glass fiber rough
Cause Analysis
POE soft, cannot coat glass fiber; interface poor, floating fiber phenomenon
Solution
1) KH-570 coupling agent treatment of glass fiber; 2) POE-g-MAH 2-3wt%; 3) Lower injection speed to reduce floating fiber; 4) Mold temperature 50°C; 5) Glass fiber 0.5-1mm
Key Takeaway
POE floating fiber is caused by insufficient coating and poor interface; coupling agent and lowering speed are key
