Hollow glass microspheres micro spheres bubbles beads

Hollow glass microsphere is a tiny sphere with high ball-type rate. Its ball-bearing effect can
improve its mobility and reduce the viscosity and internal stress of resin mixture.

It is also called flying ash hollow ball, grayish white, thin wall and hollow, very light weight.

It has fine grain, hollow, light weight, high strength, wear resistance, high temperature resistance, insulation, flame retardant insulation and other properties, is widely used in one of the refractory raw material industry.

Potential Applications  :

Light cement slurry, Paint and coating, Putty, Adhesives, Sport Appliances,
Floating materials Polyurethane, Artificial Marble, Epoxy Tooling Board,
Ceramic Materials, Emulsion explosives
Synthetic foam
