Functional Fillers
Closed cell perlite based hollow microspheres TRI-SPHERES®
Description
TRI-SPHERES® are hollow multi-cellular microspheres with a popcorn structure on a silicate basis. TRI-SPHERES® serve as functional lightweight fillers. Their heat resistance is up to 1,500 °C. Their compressive strength ends at 3,260 PSI / 22.5 Mpa. With a view to any shear forces occurring during the incorporation, their multi-cellular structure avoids that all spheres are destroyed at high forces. TRI-SPHERES® are marked by a clear bright colour.
Application
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® 270, 300 and 352 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.

tri-spheres©.pdfCenospheres OMEGA-SPHERES®
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.
