(EN) RESIN FOAM AND FOAMED SEALING MATERIAL
(FR) MOUSSE DE RÉSINE ET MATÉRIAU D'ÉTANCHÉITÉ MOUSSÉ
(JA) 樹脂発泡体及び発泡シール材
要約
(EN) Provided is a resin foam having excellent dust-proof performance particularly under dynamic environments. This resin foam is characterized by having 65% or greater of a thickness recovery ratio that is defined as follows. Thickness recovery ratio: the ratio of a thickness of the resin foam when the resin foam is compressed in an atmosphere having a temperature of 23˚C for one minute in the thickness direction in such a manner that the thickness of the resin foam becomes 20% of the initial thickness, the compression is removed in an atmosphere having a temperature of 23˚C, and the thickness is measured 1 second after the removal of the compression to the initial thickness of the resin foam.
(FR) L'invention concerne une mousse de résine ayant une excellente performance anti-poussière, en particulier dans des environnements dynamiques. Cette mousse de résine est caractérisée en ce qu'elle présente un rapport de récupération d'épaisseur de 65% ou plus, lequel est défini comme suit. Rapport de récupération d'épaisseur : le rapport d'une épaisseur de la mousse de résine lorsque la mousse de résine est comprimée dans une atmosphère ayant une température de 23°C pendant une minute dans la direction de l'épaisseur d'une manière telle que l'épaisseur de la mousse de résine devient 20% de l'épaisseur initiale, la compression est retirée dans une atmosphère ayant une température de 23°C, et l'épaisseur est mesurée 1 seconde après le retrait de la compression jusqu'à l'épaisseur initiale de la mousse de résine.
(JA)  防塵性能、特に動的環境下での防塵性能に優れる樹脂発泡体を提供する。 本発明の樹脂発泡体は、下記で定義される厚み回復率が65%以上であることを特徴とする。 厚み回復率:樹脂発泡体を、23℃の雰囲気下、初期厚みに対して20%の厚みとなるように厚み方向に1分間圧縮した後、23℃の雰囲気下、圧縮状態を解除し、圧縮状態解除1秒後の厚みの初期の厚みに対する割合
