Title:
延伸成型用ポリエチレン原反シートの製造方法及び延伸ポリエチレンシートの製造方法
Document Type and Number:
Japanese Patent JP4323650
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for manufacture of a stretch molding polyethylene raw fabric sheet used for obtaining an oriented polyethylene sheet having a mechanical strength equal to that of a glass fiber reinforced sheet, and a method for manufacture of the oriented polyethylene sheet using that. SOLUTION: A stretch molding polyethylene raw fabric sheet capable of being highly oriented which is obtained by being kept for a specific time within a temperature range lower by 0-20 deg.C than a melting point in a course wherein a polyethylene is shaped into a sheet-like product and solidified by cooling; and a method for manufacture of an oriented polyethylene sheet excellent in mechanical strength by high stretching times wherein the stretch molding polyethylene raw fabric sheet is rolled and stretched thereafter, are obtained.
