Title (EN) DOUBLE-SIDED ADHESIVE TAPE
(FR) BANDE ADHÉSIVE DOUBLE FACE
(JA) 両面粘着テープ
Abstract:
(EN) This double-sided adhesive tape is obtained by providing both surfaces of a polyolefin resin foam sheet, which is obtained by foaming an expandable composition that contains a polyolefin resin, with adhesive layers. With respect to this double-sided adhesive tape, the average foam cell diameter of the polyolefin resin foam sheet is from 25 to 150 μm; and at least one of the adhesive layers has an adhesive force of from 1.1 to 23 N/25 mm at 25°C as determined in accordance with JIS Z0237 (2009). Consequently, the present invention is able to provide a double-sided adhesive tape which has excellent reworkability, and which exhibits good waterproof properties even after reworking.
(FR) La présente invention concerne une bande adhésive double face obtenue en fournissant des couches adhésives aux deux surfaces d’une feuille de mousse de résine de polyoléfine, qui est obtenue par moussage d’une composition expansible qui contient une résine de polyoléfine. Par rapport à cette bande adhésive double face, le diamètre moyen des alvéoles de mousse de la feuille de mousse de résine de polyoléfine est de 25 à 150 µm ; et au moins l’une des couches adhésives a une force adhésive de 1,1 à 23 N/25 mm à 25 °C telle que déterminée selon la norme JIS Z0237 (2009). Par conséquent, la présente invention permet de fournir une bande adhésive double face qui présente une excellente aptitude au repositionnement, et qui fait preuve de bonnes propriétés d’étanchéité à l’eau même après le repositionnement.
(JA) 本発明の両面粘着テープは、ポリオレフィン樹脂を含む発泡性組成物を発泡させてなるポリオレフィン系樹脂発泡シートの両面に粘着剤層を設けた両面粘着テープである。両面粘着テープにおいて、前記ポリオレフィン系樹脂発泡シートの平均気泡径は、25~150μmであり、前記粘着剤層の少なくとも一方についてJIS Z0237-2009に準拠して測定した25℃における粘着力は1.1~23N/25mmである。本発明によれば、リワーク性に優れ、且つリワーク後であっても良好な防水性を示す両面粘着テープを提供することができる。
