FDA-Approved Microspheres

What makes a microsphere FDA-approved? In order to tell whether the microsphere can be used in cosmetics, food, or medical devices it is important to look at the raw materials that are incorporated into the microsphere during manufacturing process.? For example, unpigmented or clear polyethylene microspheres supplied by Cospheric in sizes from 10 micron to 1000 micron meet the…

Phosphorescent Microspheres – Long Afterglow Particles

Phosphorescent microspheres in particle sizes 10 to 600 microns are now available from Cospheric LLC. These phosphorescent particles are 90% spherical and appear to be off-white under ordinary daylight or regular room illumination.? However, when the lights are turned off these phosphorescent particles exhibit phosphorescent yellow-green after-glow. The spheres have tight particle size distributions and are > 90% within…

Technical Characteristics of PMMA Microspheres

PMMA micropsheres or polymethylmethacrylate microspheres are often referred as acrylic microspheres.? 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. It has somewhat poor solvent resistance. PMMA spheres are soluble in organic solvents such as acetone, benzene, or halogenated hydrocarbons. Though flammable, PMMA…
