摘要: Glass formulations, and a method of converting such glass formulations to glass beads having a refractive index of at least 1.59 and a high level of retroreflectivity, are provided. The methods and formulations provide beads also having high levels of resistance to degradation by environmental exposure.

摘要: Glass microspheres containing a substantial percentage of spheres having two or more optically visible gas bubbles per sphere provide a high level of whitening to composite materials containing them. The volume of gas bubbles is between 8 and 35 percent of the volume of the spheres on average, and the spheres exhibit good resistance to breakage upon exposure to high pressures such as may be encountered in polymer extrusion processes. The spheres have a median particle diameter of between 5 and 100 μm, and at least 10% by number of the spheres incorporate at least two gas bubbles.

摘要: This invention relates to inorganic microspheres having a relatively narrow particle size distribution, which may be prepared by spheridization of zeolite crystals. The microspheres are particularly useful for whitening polymer compositions and in other filler applications.
摘要翻译: 本发明涉及具有相对窄的粒度分布的无机微球,其可以通过沸石晶体的球化来制备。 微球对于增白聚合物组合物和其它填料应用是特别有用的。
