Hollow glass microspheres are thin-walled micro-borosilicate glass beads. They are chemically very stable, have a very low density and high compressive strength.
Glues
Weight reduction; sound absorption; reduced contraction; improved thermal and electrical insulation.
Finishes
Cost reduction; high filling degree with low viscosity; improved flow properties, gloss and processability; higher hardness and abrasion resistance; reduction of UV degradation.
Injection moulding/extrusion
Improved level of detail; cost reduction; improved rigidity; reduced warpage.
Fillers
Weight reduction; cost reduction; sound reduction; reduced contraction; improved thermal and electrical insulation.
Sealants
Weight reduction; cost reduction; sound reduction; reduced contraction; improved thermal and electrical insulation.
