Road markings lit up by car headlights at night, high-visibility safety garments worn by traffic police and sanitation workers, eye-catching traffic signs inside tunnels-all these safety visual effects in low-light environments rely on tiny optical components: glass beads.
As a leading Chinese manufacturer of reflective materials, YGM has developed a complete industrial chain since its establishment in 2005, encompassing reflective sheeting, reflective heat transfer vinyl, reflective tape for clothing, and a range of other reflective products using glass beads as raw materials. Its products have obtained numerous international authoritative certifications, including EN ISO 20471, ANSI 107, OEKO-TEX Standard 100, and ISO9001, serving various sectors worldwide, including road safety, occupational safety, and fashion apparel.
Glass beads rely on reflective optics to reflect incident light back to the source. The refractive index (RI) is the most crucial indicator distinguishing the performance of glass beads; a higher refractive index results in stronger reflectivity.
I. Glass Beads for Traffic Safety: Safeguard Road Travel
- 5 Series Glass Beads (Low Refractive Index)
- 6 Full-Life-Cycle Glass Beads
- 7 Medium-Refractive-Index High-Performance Glass Beads
- 9 High-Retro-Reflective Glass Beads
- 2 Glass Beads (For Reflective Sheeting Only)
- AWP Wet-State Retro-Reflective Elements｜6th-Generation Rainy-Night Glass Beads
II. Glass Beads for Personal Safety Protection: Foundation of Personal Protection
RI1.93 High–Refractive–Index Glass Beads with fine and uniform particle size and stable optical properties; they are core substrates for textile-based reflective materials. This bead series is embedded inside YGM’s reflective fabric, reflective heat transfer vinyl (HTV), reflective webbing and reflective tape to achieve reflective effects.
III. Downstream Reflective Product Portfolio Powered by YGM Glass Beads
Reflective Heat Transfer Vinyl: Silver reflective, colorful reflective, rainbow reflective, segmented reflective, etc; can be heat-transferred onto various fabrics for use in workwear logos and trendy apparel.
Reflective Tape: Includes silver/grey reflective tape, flame-retardant reflective tape, sew-on reflective webbing tape and perforated reflective tape. Suitable for fire-fighting suits, workwear, bags, shoes & hats.
Reflective Fabrics:Includes silver reflective, rainbow holographic, and printed reflective fabrics for high-visibility safety garments and fashion brand textiles.
Traffic Reflective Sheeting: Bead-engineered engineering-grade, advertising-grade and license-plate-grade reflective sheeting for traffic signs, billboards and vehicle warning marks.

V. Summary
Tiny glass beads-their refractive index, sphericity, particle size, and surface treatment processes-each parameter directly determines the final safety effect. From road traffic safety to outdoor worker protection and innovative fashion apparel, the proper selection of glass beads is a crucial link in ensuring safety in low-light environments.
