In order to transport or store flatglass or floatglass, a separating medium must be applied between the panes to prevent the glass sheets from blocking due to adhesion forces. This is the only way to easily separate the panes again for subsequent production processes.
The interleaving powder series esplas and esbal are developed especially for powdering in the flatglass or floatglass line.
The basis for the powder series esplas is polymethyl methacrylate (PMMA) or polyethylene (PE). Thanks to a specific production process, the particles have a unique grain structure. The irregular shape of the particles affects the gliding effect of the panes and favours excellent adhesion of the particles on the pane.
For some applications however, round particles can be beneficial. For this we offer the esbal powder series of polymethyl methacrylate (PMMA) in bead form.
Glass surfaces may corrode during transport or storage. In order to counteract this, if necessary, a specific agent can be added to the polymer particles. Depending on climatic conditions, such additions can range between 10 and 50%.
The particle size distribution is also important for effective powder application. Powders with an average particle diameter of approximately 60, 80, 130 and 150 µm have proved successful. The powders with lower particle diameter offer some advantages due to better adhesion.
Different particle shapes also influence the diverse fields of application.
This results in a variety of different products. We support our customers in identifying the products which are best suited for their field of application.
