(JA) 熱発泡性マイクロスフェアー、並びにそれを含む組成物及び成形体
Abstract: front page image
(EN)Provided are thermally-expandable microspheres having little sag. These thermally-expandable microspheres have a structure in which a blowing agent is sealed inside an outer shell formed from a polymer, wherein, if the expansion ratio is denoted as R1 after the thermally-expandable microspheres have been treated with heat for five minutes at 150°C and then foamed by heating for two minutes at 200°C, and the expansion ratio is denoted as R2 after the thermally-expandable microspheres have been treated with heat for five minutes at 150°C and then foamed by heating for four minutes at 200°C, the ratio (%) expressed by (R2/R1) × 100 is at least 105%.
(FR)L'invention concerne des microsphères thermo-expansibles à faible affaissement. Ces microsphères thermo-expansibles présentent une structure dans laquelle un agent d'expansion est scellé à l'intérieur d'une coque externe formée à partir d'un polymère. Dans ces microsphères, si le taux d'expansion est désigné par R1 après le traitement thermique des microsphères thermo-expansibles pendant cinq minutes à 150°C, puis l'expansion par chauffage pendant deux minutes à 200°C, et si le rapport d'expansion est désigné par R2 après le traitement thermique des microsphères thermo-expansibles pendant cinq minutes à 150°C, puis l'expansion par chauffage pendant quatre minutes à 200°C, le rapport (%) exprimé par (R2/R1) × 100 est d'au moins 105%.
(JA)ヘタリ現象の少ない熱発泡性マイクロスフェアーを提供すること。 重合体から形成された外殻内に発泡剤が封入された構造を持つ熱発泡性マイクロスフェアーであって、熱発泡性マイクロスフェアーの、150℃で5分間の熱処理後、200℃で2分間加熱発泡したときの発泡倍率をR1とし、150℃で5分間の熱処理後、200℃で4分間加熱発泡したときの発泡倍率をR2としたとき、(R2/R1)×100で表した比率(%)が、105%以上である、熱泡性マイクロスフェアー。
