TRAMACO’s microspheres are filled with a physical foaming agent that is encapsulated in a polymeric shell and strongly expands under the influence of heat while keeping the increased volume during cooling. Applications include underbody coatings. By using these microspheres, very low densities and highly homogeneous, closed-cell foam structures can be produced. Already pre-expanded microspheres are brand-new in TRAMACO’s portfolio. By application of these ultra-light fillers, with densities below 30 kg/m³, cell structures can also be created in materials that do not allow expandable microspheres or conventional chemical foaming agents in their processing operations, such as paints, lacquers, coatings or thermosets.
