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 which has a loss tangent (tanδ) of 0.35 or more but less than 0.60 at 230°C as determined by melt viscoelasticity measurement.
(FR)
La présente invention concerne une membrane microporeuse en polyoléfine qui a une tangente de perte (tanδ) de 0,35 ou plus mais inférieure à 0,60 à 230 °C telle que déterminée par mesure de viscoélasticité à l'état fondu.
(JA)
