Lightweight filler and blowing agent in one
Expancel Microspheres is a lightweight filler and blowing agent all in one. Its high performance in these two functions opens up a world of surprising possibilities. Using Expancel Microspheres improves the properties of your product, and also enables considerable savings in the cost of materials, production and finishing, handling and transportation. For manufacturers, it means economy, consistency and control. For consumers, it means quality and satisfaction.
The lighter side of performance
Expancel Microspheres can significantly reduce the weight of a product while creating the look and feel needed for an attractive product. As a lightweight filler, it can achieve very low densities. Our standard expanded microspheres (Expancel DE(T) and WE) have densities as low as 25 kg/m³ depending on product. This is much lower than, for example, glass microspheres. Even small proportions of Expancel Microspheres will reduce the density of the end product to a significant degree. Binder demand is low, so the amount of binder in the end product can be reduced with no loss of desired properties.
Reducing binder also saves costs. Expancel Microspheres is used as a lightweight filler in many applications today, including elastomeric cool roof coatings, paint, cultured marble, underbody coatings and sealants, polyester putties and many more. Its many benefits include cost reduction, low density, flexibility, sandability and a smoother surface with no pinholes.
Perfecting the structure
Unexpanded Expancel Microspheres is an excellent blowing agent that gives a highly controlled foaming, resulting in a fine and uniform cell structure. You can avoid the use of chemical blowing agents and achieve excellent performance at low viscosities. Expancel Microspheres can also be combined with chemical blowing agents if required.
Expancel Microspheres is used as a blowing agent in many applications today, including shoe soles, wine corks (plastic and agglomerated), printing inks, food packaging and weather strips for cars. As a blowing agent, Expancel Microspheres delivers many essential benefits, including a fine cellular foam structure, outstanding stability during processing, shorter cycle times and an attractive surface finish.
