Title (EN) DOUBLE-SIDED ADHESIVE TAPE
(FR) RUBAN ADHÉSIF DOUBLE FACE
(JA) 両面粘着テープ
Abstract:
(EN) The purpose of the present invention is to provide a thin double-sided adhesive tape exhibiting excellent light-blocking properties, and to be used in order to adhere and affix a component constituting a portable electronic device to the device body. The present invention pertains to a double-sided adhesive tape having an acrylic adhesive layer on both surfaces of a substrate, wherein: the substrate comprises a polyolefin foam containing a polyolefin resin and a colorant, the content of the colorant constituting at least 0.1 parts by weight relative to 100 parts by weight of the polyolefin resin; the substrate has a density of 0.4-0.8 g/cm3, a thickness of 100-250μm, and an average cell wall thickness of 4μm or more; and the overall thickness of the double-sided adhesive tape is 400μm or less.
(FR) L'objet de la présente invention est de pourvoir à un mince ruban adhésif double face présentant d'excellentes propriétés de blocage de la lumière, et destiné à être utilisé pour faire adhérer et fixer un composant constituant un dispositif électronique portable au corps du dispositif. La solution selon la présente invention porte sur un ruban adhésif double face comportant une couche acrylique adhésive sur les deux faces d'un substrat, caractérisé en ce que : le substrat comprend une mousse polyoléfine contenant une résine polyoléfine et un colorant, la teneur en colorant représentant au moins 0,1 partie en poids pour 100 parties en poids de résine polyoléfine; le substrat a une densité de 0,4 à 0,8 g/cm3, une épaisseur de 100 à 250 μm, et une épaisseur moyenne de paroi d'alvéole de 4 μm ou plus; l'épaisseur globale du ruban adhésif double face étant de 400 μm ou moins.
(JA) 本発明は、携帯電子機器を構成する部品を機器本体に接着固定するために用いられる、薄くかつ遮光性に優れた両面粘着テープを提供することを目的とする。 本発明は、基材の両面にアクリル粘着剤層を有する両面粘着テープであって、前記基材は、ポリオレフィン樹脂と、前記ポリオレフィン樹脂100重量部に対して0.1重量部以上の着色剤とを含有するポリオレフィン発泡体からなり、前記基材は、密度が0.4~0.8g/cm、厚みが100~250μm、平均セル壁厚みが4μm以上であり、両面粘着テープの総厚みが400μm以下である両面粘着テープである。
