Title
(EN) ADHESIVE TAPE
(FR) RUBAN ADHÉSIF
(JA) 粘着テープ
Abstract
(EN)
The present invention provides an adhesive tape in which it is possible to obtain high levels of both adhesiveness and flame retardance, even when the thickness is reduced. This adhesive tape is provided with a substrate and an adhesive layer provided on one or both sides of the substrate, wherein the adhesive tape is characterized in that: the adhesive tape has a thickness of 30 μm or below when the adhesive tape is a one-sided adhesive tape; the adhesive tape has a thickness of 50 μm or below when the adhesive tape is a double-sided adhesive tape; the adhesive tape has a flame retardance of at least a level conforming to VTM-0 in a test according to UL94 standards; the adhesive layer has a thickness of 20 μm or below; and the adhesive constituting the adhesive layer contains a flame retardant in which the particle diameter D95 corresponding to cumulative 95% from the small-diameter side of the cumulative granularity distribution is 20.0 μm or below.

La présente invention concerne un ruban adhésif avec lequel il est possible d'obtenir des niveaux élevés d'adhésivité et de retard de flamme, même lorsque l'épaisseur est réduite. Le ruban adhésif de la présente invention inclut un substrat et une couche adhésive disposée sur un ou sur les deux côtés dudit substrat, le ruban adhésif étant caractérisé en ce que : le ruban adhésif a une épaisseur de 30 µm ou moins lorsque le ruban adhésif est un ruban adhésif unilatéral ; le ruban adhésif a une épaisseur de 50 µm ou moins lorsque le ruban adhésif est un ruban adhésif double face ; le ruban adhésif offre un retard de flamme d'un niveau au minimum conforme à VTM-0 dans le cadre d'un test répondant aux normes UL94 ; la couche adhésive a une épaisseur de 20 µm ou moins ; et l'adhésif constituant la couche adhésive contient un agent ignifuge dans lequel le diamètre de particule D95, qui correspond à un total cumulatif de 95% de la distribution de granularité cumulative en partant des valeurs les plus faibles, est de 20,0 µm ou moins.
