POE toughened PP flowability greatly reduced

문제 현상

POE/PP MFR drops from 15 to 3-5, injection short shot

원인 분석

POE molecular weight high and viscosity large, adding 15-20wt% viscosity rises significantly

해결 방법

1) Low viscosity POE MFR>5; 2) Temperature 185-200°C; 3) Oxidized PE wax 0.3-0.5wt%; 4) POE+talc synergy

핵심 요약

Flowability reduction can be balanced with low-viscosity grades and processing aids
