POE toughened PP low-temperature impact insufficient

문제 현상

POE/PP -20°C impact only 2-3kJ/m², low temperature not up to standard

원인 분석

PP low-temperature embrittlement, Tg about -10°C; POE Tg>-50°C, low-temperature toughening weakened

해결 방법

1) Low Tg POE, Tg about -55°C; 2) POE increased to 20-25wt%; 3) POE-g-MAH 2-3wt%; 4) POE+EPDM composite toughening

핵심 요약

Low-temperature toughening requires lower Tg and stronger interfacial adhesion
