Microspheres, Spheres, Micro beads - PMMA - Poly(methyl Methacrylate) - Acrylic Spherical Particles

PMMA polymer is an amorphous, transparent and colorless thermoplastic that is hard and stiff. It has good abrasion and UV resistance and excellent optical clarity. PMMA spheres are soluble in organic solvents such as acetone, benzene, or halogenated hydrocarbons. Though flammable, PMMA material has low smoke emission.PMMA microspheres have good biocompatibility which allows the particles to be used in many medical and biochemical applications. PMMA spheres also make an effective bondline spacer for applications where slight deformation of the spacer particle under pressure is desired.

PMMA microspheres have good bio-compatibility which allows the particles to be used in many medical and biochemical applications.

*Please note that due to the nature of the manufacturing process, some lots of this material may have a small amount of fines (sub 5 micron particles) that attach to the spheres and give an appearance of non-smooth surface.

Particles in Size Range: >90%
Sphericity: >90%
Density: 1.1-1.3g/cc

Poly(methyl methacrylate) or PMMA is less hydrophobic than polystyrene and reported to show reduced nonspecific protein and peptide binding. The density of these beads, 1.19 g/cc, is considerably heavier than polystyrene particles, allowing more rapid separation and making them easier to concentrate by centrifugation. The particles typically have a hydrophilic anionic surface with refractive index of 1.48.
