Title (EN) LARGE-DIAMETER HEAT-EXPANDING MICRO-SPHERES, AND METHOD FOR PRODUCING SAME
(FR) MICROSPHÈRES THERMO EXPANSIBLES DE GRAND DIAMÈTRE ET PROCÉDÉ DE PRODUCTION DE CELLES-CI
(JA) 大径の熱発泡性マイクロスフェアー、及びその製造方法
Abstract: front page image
(EN)The purpose of the present invention is to provide heat-expanding micro-spheres with which it is possible to form large-diameter heat-expanding foam beads which are lightweight and which have improved strength and cushioning properties. Heat-expanding micro-spheres having an average particle size before foaming (D50) of 100-500μm, and a coefficient of variation (logarithmic scale) of particle size distribution before foaming not exceeding 15%, and having a foaming agent sealed inside the outer shell of a polymer.
(FR)L'invention concerne des microsphères thermo expansibles qui permettent de former des particules expansées de grand diamètre, ces particules étant légères et présentant des caractéristiques de dureté, d'amortissement etc. améliorées. Plus spécifiquement, l'invention concerne des microsphères thermo expansibles, lesquelles présentent une taille moyenne (D50) de particule avant expansion comprise entre 100 et 500μm, dont le coefficient de variation (échelle logarithmique) de la répartition de tailles de particules avant expansion est égal ou inférieur à 15%, et dans lesquelles un agent d'expansion est encapsulé dans l'enveloppe externe polymère.
(JA)軽量で改善された強度やクッション性等を有する大径の発泡粒子を形成することができる熱発泡性マイクロスフェアーを提供すること。 発泡前の平均粒径(D50)が100~500μmであり、発泡前の粒径分布の変動係数(対数スケール)が15%以下である、重合体の外殻中に発泡剤が封入された熱発泡性マイクロスフェアー。
