SiLibeadsHollow Glass Beads – SiLibeads AIR

Hollow glass balls made of borosilicate glass as filler/filling ball

Hollow glass beads are thin-walled micro-borosilicate glass beads. They are chemically very stable, have a very low density and high compressive strength.

Application Filler in the following materials:

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
