Hollow ceramic microspheres are extremely resistant hollow spheres, which are formed under the exposure of extreme heat. Temperatures over the relevant melting points are required to achieve a ceramic melting. Drops with a hollow are formed as a result of the subsequent rapid cooling process. The OMEGA-SPHERES® formed in this way are refined and fractionated in subsequent processes, thus being a high-quality raw material in your formulations.
The spheres we provide are produced at various production sites for global availability. Globally produced standard types are manufactured in the Ukraine and Germany. Special types are produced in Germany. There are further suppliers in Europe and throughout the world.
TRI-SPHERES® can be used as lightweight fillers in many different applications such as paints and coatings, foams in composites as well as in hydraulic-setting cement for construction chemistry (TRI-SPHERES® 120 XL). With a view to the optimisation of acoustic and thermal properties, TRI-SPHERES® 300 and 400 are recommended. In particular the fine TRI-SPHERES® 45XS Ultra achieves good results in partial weight reduction of PP polymer for injection mouldingwhen adding 10 – 15 % as an additive for the last step.
OMEGA-SPHERES® are hollow ceramic microspheres > 150 μm which are used as functional lightweight filler is several industries. OMEGA-SPHERES® are characterised by a high thermal and mechanic resistance and are available in different distribution particle sizes.
Because of their weight-reducing and insulating properties, OMEGA-SPHERES® are used preferentially in construction chemical products such as adhesives and sealants. They are also used as pore generators in friction and brake linings as well as in grinding and separating tools.
OMEGA-SPHERES® W are marked by a particularly high thermal resistance, low iron content and a white colour. They are available in different distribution particle sizes.
Because of their particularly high heat resistance, OMEGA-SPHERES® W are preferentially used in the refractory and foundry industries. The white colour allows their use in aesthetically demanding applications such as decorative plasters and wall paints.
THERMO-SPHERES® G are high quality hollow ceramic microspheres < 150 μm, which are characterised by a high degree of fineness as well as a particularly high mechanical strength. The products are pre-dried. Because of the high fineness, they display good grinding properties and are, therefore, highly suitable as insulation and lightweight filling materials.
THERMO-SPHERES® G are used in applications which require the use of particularly small hollow microspheres or make high demands on surface finish. This includes, apart from the use in paints and coatings, composite materials, special casting compounds and putties, adhesives and sealants.
THERMO-SPHERES® W are white, high quality hollow ceramic microspheres < 150 μm, which are characterised by a high degree of fineness as well as a particularly high mechanical strength. The products are pre-dried and usable for foundry industry. The white colour allows their use in aesthetically demanding applications such as decorative plasters and wall paints.
THERMO-SPHERES® W are used in bright applications which require the use of the smallest possible microspheres or make high demands on surface quality. This includes applications in addition to the use in paints and coatings, surfaces as well as special casting compounds and adhesives where a high whiteness is advantageous.
