Microspheres are characterized by a combination of unique properties: low density, spherical shape, high melting point and hardness, and are chemicall

The spherical shape means that it takes less resin, binder, water etc to wet out the surface of cenospheres than any other shaped filler. This results

Microspheres have a low thermal conductivity of 0.11 Wm-1K-1. As a result they have found applications in insulating refractories, oil pipeline insula

The free flowing nature of microspheres means that they are easy to handle in a factory environment. They can be easily gravity fed without blockage a

The advantages of low density are quite obvious and clear. At 0.7 g/cc cenospheres are approximately 25 % of the density of other mineral fillers but

Silica-alumina spheres inherently have very low reactivity. Their chemical composition makes them very resistant to acids and alkalis. They are neutra

Cenospheres have a high melting point of 1200 - 1600 C, which is considerably higher than synthetic glass microspheres. They are therefore excellent f

The hard surface of microspheres provides excellent erosion resistance. The glassy shell of the microspheres is totally impermeable to liquids and gas
