Monodisperse – Spacer Grade Microspheres

SLGMS 27-30um 40x

Scientists are constantly looking for narrower particle size distributions (monodispersed) of microspheres to help increase the consistency and correlation between theoretical models and verification experiments.  In an effort to fill the increasing demand for these particles Cospheric has launched a new line of spacer grade microspheres.

Monodisperse microspheres are currently offered in diameters of:   21-24um, 23-26um, 25-28um, 27-30um, 29-32um, 31-34um, 33-36um, 35-38um, 37-40um, 50-53um

Manufactured with Soda Lime Glass, monodisperse spheres are excellent for spacing epoxy bond lines that will experience high temperature.

• Degree of Roundness: >90%
• Particles in Size Range: >95%
• Density: ~2.52g/cc
• Index of refraction: ~1.51
• Softening Temperature: 730°C

What is a Microsphere?

Definition From Wikipedia,

Microsphere is a term used for small spherical particles, with diameters in the micrometer range (typically 1μm to 1000μm (1mm)). Microspheres are sometimes referred to as microparticles.

Microspheres can be manufactured from various natural and synthetic materials. Glass microspheres, polymer microspheres and ceramic microspheres are commercially available. Solid and hollow microspheres vary a lot in density and, therefore, are used for different applications. Hollow microspheres are typically used as additives to lower the density of a material. Solid microspheres have numerous applications depending on what material they are constructed of and what size they are. Continue reading “What is a Microsphere?” »
