Title (EN) CROSSLINKED POLYOLEFIN FOAM
(FR) MOUSSE DE POLYOLÉFINE RÉTICULÉE
(JA) 架橋ポリオレフィン系発泡体
Abstract:
(EN) This crosslinked polyolefin foam is obtained by crosslinking and foaming a polyolefin resin composition containing: a polyolefin resin (A); and a rubber (B) with a Mooney viscosity (ML1+4, 100℃) of 15 to 85. This crosslinked polyolefin foam contains 10 to 150 parts by mass of the rubber (B) per 100 parts by mass of the polyolefin resin (A); the thickness of the foam is 1.5mm or more and has a 25% compressive hardness of 60kPa or less; the degree of crosslinking of at least one of the surface layer parts from either face to a depth of 500μm is at least 5% greater than the degree of crosslinking of the intermediate layer part excluding the surface layer parts on both surfaces.
(FR) L'invention concerne une mousse de polyoléfine réticulée obtenue par réticulation et expansion d'une composition de résine polyoléfine contenant: (A) une résine polyoléfine; et (B) un caoutchouc dont la viscosité de Mooney (ML1+4, 100℃) est comprise entre 15 et 85. Pour 100 parties en poids de la résine polyoléfine (A) il y a de 10 à 150 parties en poids du caoutchouc (B). L'épaisseur de la mousse susmentionnée est supérieure ou égale à 1,5mm, et sa résistance à la compression de 25% égale ou inférieure à 60kPa. Le degré de réticulation d'au moins une des deux parties de surface allant des deux faces jusqu'à une profondeur de 500μm est supérieur d'au moins 5% au degré de réticulation d'une partie de couche intermédiaire dont les parties surfaces sont exclues.
(JA) 本発明の架橋ポリオレフィン系発泡体は、ポリオレフィン系樹脂(A)と、ムーニー粘度(ML1+4,100℃)が15~85であるゴム(B)とを含有するポリオレフィン系樹脂組成物を架橋発泡してなる架橋ポリオレフィン系発泡体であって、前記ゴム(B)は、前記ポリオレフィン系樹脂(A)100質量部に対して、10~150質量部含有され、前記発泡体の厚さは1.5mm以上であるとともに25%圧縮硬さが60kPa以下であり、両面から500μm深さまでの表層部の少なくともいずれか一方の架橋度が、前記両面の表層部を除いた中層部の架橋度よりも5%以上高い。
