FOAM, SOUND ABSORBING MATERIAL, BUILDING, AND VEHICLE
To provide a foam having excellent sound absorbing characteristics, a sound absorbing material having the foam, and a building and a vehicle having the sound absorbing material.SOLUTION: By foaming and curing a polyoxyalkylene-based polymer (A1)-containing base resin (A) having a reactive silicon group to produce a foam, a foam that exhibits good sound absorption characteristics over a wide frequency range of 1000 Hz to 5500 Hz is produced. Further, the foam is applied as a sound absorbing material. Furthermore, the sound absorbing material is applied to a building and a vehicle.SELECTED DRAWING: Figure 1
【課題】吸音特性に優れる発泡体と、当該発泡体を備える吸音材と、当該吸音材を備える建築物及び車両とを提供すること。【解決手段】ポリオキシアルキレン系重合体（Ａ１）を含む反応性ケイ素基を有する基材樹脂（Ａ）を、発泡及び硬化させて発泡体を製造することにより、１０００Ｈｚ〜５５００Ｈｚの幅広い周波数範囲において良好な吸音特性を示す発泡体を製造する。また、当該発泡体を吸音材に適用する。さらに、当該吸音材を、建築物及び車両に適用する。【選択図】図１
