SiLibeads® Type S

• Grinding and dispersing beads: Ideal for wet grinding in agitator ball mills. They are used for grinding dyes, pigments, ink, agrochemicals, minerals and fillers and enable particle sizes below 10 microns.
• Reflective glass beads: These play a crucial role in road safety through retro-reflection, which reflects headlight beams back to the driver and increases the visibility of road markings.
• Blasting glass beads: SiLibeads® Type S glass beads are used as abrasives for the mechanical surface treatment of wood, metal and plastic.
• Polishing agent for optical and intraocular lenses: Specially developed glass beads (Art. 45xx-R8) with improved roundness are used to polish intraocular lenses to prevent scratches and ensure a smooth surface.

• Wide range of sizes: Available in sizes ranging from 0.25 to 6.00 mm.
• High proportion of beads in the nominal size range: Ensures consistent performance.
• High roundness of the beads: dMIN / dMAX ≥ 0.95 (higher on request).
• Clean and polished surfaces: Ensures high product quality.
• High retro-reflectivity: For applications in traffic safety.
• Low process residues: Minimises contamination.
• Wide range of size fractions: Customised special sieving possible.
