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 Properties of PMMA Microspheres

PMMA Microspheres - Technical Specifications

In this article we will discuss the applications and technical properties of PMMA microspheres. What are PMMA Microspheres? PMMA micropsheres are also known as Poly(methyl methacrylate) or acrylic microspheres. PMMA, an ester of methacrylic acid (CH2=CCO2H), is a synthetic resin produced from the polymerization of methyl methacrylate. Ever since PMMA resin was discovered and first commercialized in 1930s, it…

Fluorescent Tracer Microspheres – Properties and Applications

Fluorescent Tracer Particles

Fluorescent microspheres are round spherical particles that emit bright colors when illuminated by UV light. Ability to emit intense color under UV (black light) illumination provides contrast and visibility of microspheres relative to background materials.
