MICROPOROUS POLYETHYLENE MEMBRANES HAVING LOW FUSING TEMPERATURES |
摘要 |
<p>A polyethylene microporous film which is composed of a linear copolymeric polyethylene having a melt index (MI) of less than 0.1 and a propylene unit content of 0.1 to 4 mol % and which has a fuse temperature of less than 136 DEG C. A polyethylene microporous film which is composed of a mixture of a linear copolymeric polyethylene having a melt index (MI) of less than 0.1 and a propylene unit content of 0.1 to 4 mol % and a high density polyethylene having a comonomer unit content of less than 0.1 mol %, said mixture having a weight average molecular weight of 250,000 to 700,000 and a propylene unit content of 0.1 to 4 mol %, and which has a fuse temperature of less than 136 DEG C.</p> |
