3M中空玻璃微球综述

一． 3M中空玻璃微球的物性

* 形状                壁薄的单个空心球体                                 降低密度，减轻重量

* 成分                碱石灰硼硅酸盐玻璃                                 粘度低、提高流动性

* 水溶性            不溶于水                                                     成本经济，部分取代树脂

* 颜色                纯白色                                                        不吸收树脂、高填充率

* 密度                0.125-0.60g/cc                                         优秀的隔音性能

* Ph值               碱性—9.5                                                  低热传导系数（0.003-0.01BTU/in.hr. ℉），隔热作用

* 抗压强度       1.72MPa – 124.02 MPa                         低介电常数(1.2-2.0)

* 软化温度        600 ℃                                                        减少收缩降低翘曲，增加产品尺寸稳定性

                                                                                              防止开裂

                                                                                              防止玻纤外露
