Glass Beads manufactured from premium quality
soda lime glass.
Plastic:
Used as a reinforcing filler in thermoplastic
and thermosetting moulding compounds.
Improves stiffness, heat distortion, shrinkage and flow
properties.
Surface Treatments:
Chemically inert, non-magnetic, non-inflammable and
non-explosive they may be used to remove surface
contaminants prior to treatment, enabling
surfaces to be cleaned, textured, decorated or peened
without damage to the base material.
