Glass Microspheres as Bondline Spacers
Posted by Oct 21, 2016on
Glass microspheres have a wide array of uses in many different applications. They are utilized in numerous industry applications from research, medicine, aerospace, and adhesive to name a few. The spheres are generally a few microns up to mm sized in diameter.
Glass spheres have a low thermal conductivity which makes them suitable for high temperature applications and solid spheres have high compression strengths to withstand certain mechanical pressures.
Precision glass microspheres with high spherical quality and narrow particle size distributions can be highly effective in adhesive applications as bondline spacers to maintain a controlled gap. The crush strength of the beads incorporated into adhesives allows two parts to be pressed together while maintaining the desired bond gap and eliminating excess adhesive from being extruded during the process.
Other applications for glass microspheres consist of calibration standards, filter beds, and fillers.
