    • The present invention relates to a modified form of alumina hydrate filler, thermosetting and thermoplastic compositions having improved workability and mechanical properties containing such filler and methods of manufacturing such modified alumina hydrate filler. More specifically, the invention provides for the admixture of modified alumina hydrate crystals with a resinous composition in which the individual alumina hydrate crystal edges are substantially rounded, have a mean crystal size of less than about 35 microns and less than about 0.1% by volume of alumina hydrate crystals have a diameter of less than 2 microns. The resulting compositions have improved viscosity properties and exhibit good bending strength and flame retardant characteristics.
    • 本发明涉及氧化铝水合物填料的改性形式,其具有改进的可加工性和包含这种填料的机械性能的热固性和热塑性组合物以及制造这种改性氧化铝水合物填料的方法。 更具体地,本发明提供了改性氧化铝水合物晶体与树脂组合物的混合物,其中各个氧化铝水合物晶体边缘基本上是圆形的,其平均晶体尺寸小于约35微米且小于约0.1体积% 氧化铝水合物晶体的直径小于2微米。 所得组合物具有改进的粘度性能并且表现出良好的弯曲强度和阻燃特性。
