Monosized polymer beads 

Introducing Spheromers^®

Spheromers® are acrylic microbeads with an extremely narrow particle size distribution.  The unique manufacturing process allows for narrow particle size distribution directly from the reactor, at industrial scale. Spheromers® are perfectly spherical beads made of crosslinked polymethyl methacrylate (PMMA), with exceptionally homogeneous properties and batch reproducibility.
Spheromers® are available at different grades, with particle diameter ranging from 6 µm to 60 µm. The Coefficient of Variation (CV) of the main peak is typically between 1 – 3 %. For an overview of the different Spheromers® products, click here. 

Key properties of Spheromers® include

• High mechanical strength
• High transparency 
• High thermal resistance (260°C)
• Excellent UV-stability
• Good compatibility with most resins and solvents used in coatings, plastics and adhesives
• Refractive index measured to 1.48

Being monosized, Spheromers® provide the opportunity to tailor performance of your material, whether that is a coating, a plastic, an adhesive, or something completely different. Take advantage of the extremely narrow size distribution to control thickness, or utilize the homogeneous properties to provide predictable, consistent results.
