Dispensing of microspheres can be a difficult task. When utilizing microspheres as a filler for standard mixing and dispensing machines, a breakage rate of up to 80% can occur, depending upon factors such as pump choice, material viscosity, material agitation, and temperature. Customized dispensers for microsphere-filled materials may reduce the microsphere breakage rate to a minimal amount. A progressive cavity pump is the pump of choice for dispensing materi… Web3M glass bubbles are high-strength, low-density hollow glass microspheres made from soda-lime borosilicate glass. They are nonporous, chemically stable and provide excellent water and oil resistance. Strong enough to survive processing, they can be incorporated into a wide range of polymers for density reduction.
