Breakthrough product applications with Lightweight fillers
Which capabilities would you like to transfer to your product? Do you envisage distinctive product properties, but the right ingredient or medium is missing? Then the MAGNESIA hollow microspheres might be the right solution for your field of application.
Under the tradename MagSpheres®, MAGNESIA supplies lightweight fillers for use in medical research, aerospace, construction chemistry as well as for insulation materials, plastics and environment. Various types of hollow bodies are available in selected grain size ranges and can be used mineral- and polymer-bound.
Which product idea would you like to implement? With the micro hollow spheres MagSpheres® from MAGNESIA you get much closer to your target.
MagSpheres® impress with quality and technical ingenuity
Our team of experts has many years of market experience and supports you in optimizing your product developments. With the hollow microspheres from MAGNESIA your products will reach new spheres and make a name for themselves in the market. Based on your ideas and defined parameters, we will work together to find the ideal solution for your technical challenge from for example the following MagSpheres® series:
- The MagSpheres® C series are ceramic hollow microspheres that serve as functional lightweight fillers. They are characterized by their very high temperature resistance and mechanical stability.
- The hollow glass spheres of the MagSpheres® G series stand out due to their low density with maximum compression strength. In addition, the MagSpheres® G series impresses with its excellent hydrolytic resistance.
- The perlites of our MagSpheres® P series are different from conventionally produced perlites. Through a new manufacturing process, they are built up almost closed-cell without the use of additional raw materials. This results in perlites that are characterized by low water absorption.
All MagSpheres® series are chemically inert raw materials. This means that all types of MagSpheres® can be individually combined with each other based on your requirements - there are no mutual chemical reactions. So, with regard to the product properties of the different MagSpheres® series, we will advise you according to the motto “Combine the best of all worlds”.
MagSpheres®: Diverse areas of application for your product portfolio
