Title
(EN) HIGH-FREQUENCY DIELECTRIC HEATING ADHESIVE SHEET
(FR) FEUILLE ADHÉSIVE CHAUFFANTE DIÉLECTRIQUE À HAUTE FRÉQUENCE
(JA) 高周波誘電加熱接着シート
Abstract
(EN) A high-frequency dielectric heating adhesive sheet (1A) having an adhesive layer (10) containing at least a thermoplastic resin (A) and a dielectric material that generates heat due to the application of a high-frequency electric field, wherein: the adhesive layer (10) contains a silane-modified polyolefin as the thermoplastic resin (A); and the MFR of the thermoplastic resin (A) at 190°C is 2-50 g/10 min, inclusive.
(FR) L'invention concerne une feuille adhésive chauffante diélectrique à haute fréquence (1A) ayant une couche adhésive (10) contenant au moins une résine thermoplastique (A) et un matériau diélectrique qui génère de la chaleur en raison de l'application d'un champ électrique à haute fréquence, la couche adhésive (10) contenant une polyoléfine modifiée par silane en tant que résine thermoplastique (A) ; et l'indice de fluidité à chaud de la résine thermoplastique (A) à 190 °C étant de 2 à 50 g/10 min, inclus.
(JA) 熱可塑性樹脂(A)及び高周波電界の印加により発熱する誘電材料を少なくとも含有する接着層(10)を有する高周波誘電加熱接着シート(1A)であって、接着層(10)は、熱可塑性樹脂(A)としてのシラン変性ポリオレフィンを含有し、熱可塑性樹脂(A)の190℃におけるMFRが2g/10min以上、50g/10min以下である、高周波誘電加熱接着シート(1A)。
