Poly(methyl methacrylate), PMMA, or acrylic microspheres and spheres are spherical polymer beads that are a transparent thermoplastic synthesized from methyl methacrylate polymer. PMMA microbeads are known for high impact and heat resistance, and good tensile and flexural strength. These strong yet lightweight polymer microspheres are often used as spacers, fillers, and reference particles for a variety of specialty applications in life sciences, medical technology, MEMS, optics and development of high performance composites.

See link for research articles involving our PMMA microspheres.
