Title (EN) ADHESIVE SHEET
(FR) FEUILLE ADHÉSIVE
(JA) 粘着シート
Abstract:
(EN) Provided is an adhesive sheet having good adhesion in a normal state, excellent release properties when releasing from an adherend, and excellent nonflammability. This adhesive sheet is provided with an adhesive layer having a surface A in which the adhesive force thereof is decreased by an external stimulus, the adhesive force XA1 with respect to SUS304BA at 23°C of the surface A prior to the external stimulus being at least 10 N/20 mm, the adhesive force XA2 with respect to SUS304BA at 23°C of the surface A being made less than 8 N/20 mm by the external stimulus, and the adhesive sheet having flame nonflammability corresponding to V-0 in a test in accordance with a UL94 vertical flame test.
(FR) L'invention concerne une feuille adhésive ayant une bonne adhérence à l'état normal, d'excellentes propriétés de libération lors de la libération d'un support, et une excellente non-inflammabilité. Cette feuille adhésive présente une couche adhésive dotée d’une surface (A) dans laquelle sa force adhésive est diminuée par un stimulus externe, la force adhésive XA1 par rapport à SUS304BA à 23 °C de la surface (A) avant le stimulus externe étant d'au moins 10 N/20 mm, la force adhésive XA2 par rapport à SUS304BA à 23 °C de la surface (A) étant diminuée jusqu’à moins de 8 N/20 mm par le stimulus externe, et la feuille adhésive ayant une ininflammabilité de flamme correspondant à V-0 en essai conformément à un essai vertical d’inflammabilité UL94.
(JA) 常態においては良好な粘着性を有し、被着体から剥離する際の剥離性に優れ、かつ、優れた難燃性を有する粘着シートを提供する。 本発明の粘着シートは、外部刺激により粘着力が低下する面Aを有する粘着剤層を備える、粘着シートであって、該外部刺激を与える前の該面Aの23℃におけるSUS304BAに対する粘着力XA1が、10N/20mm以上であり、該外部刺激を与えることにより、該面Aの23℃におけるSUS304BAに対する粘着力XA2が、8N/20mm未満となり、UL94垂直燃焼試験に準じた試験においてV-0相当の難燃性を有する。
