Title (EN) POLYOLEFIN MICROPOROUS MEMBRANE
(FR) MEMBRANE MICROPOREUSE EN POLYOLÉFINE
(JA) ポリオレフィン微多孔膜
Abstract:
(EN) A polyolefin microporous membrane has a piercing elongation of 2.30 mm or lower and the temperature of the stress variation point is 80.0°C or higher and the stress peak value is 1.8 g or lower in thermomechanical analysis (TMA) of the width direction of the polyolefin microporous membrane.
(FR) Cette invention concerne une membrane microporeuse en polyoléfine ayant un allongement au perçage de 2,30 mm ou moins, une température de point de variation de contrainte de 80,0 °C ou plus et une valeur de pic de contrainte de 1,8 g ou moins dans une analyse thermomécanique (TMA) pratiquée dans le sens de la largeur de ladite membrane microporeuse en polyoléfine.
(JA) ポリオレフィン微多孔膜が、2.30mm以下の突刺伸度を有し、ポリオレフィン微多孔膜の幅方向の熱機械分析(TMA)測定において、応力変異点の温度が80.0℃以上であり、かつ応力ピーク値が1.8g以下である。
