Reflective Glass Beads (Gray, White)

Shanghai Huijing Sub-Nanoscale New Material Co., Ltd. produces reflective glass beads, which are the core material for manufacturing reflective fabrics, reflective films, reflective coatings, and prints—new types of light-functional composite materials. These beads exhibit retroreflective properties, creating a strong retroreflection effect without requiring an external power source. They are widely used in roads, ports, mines, fire safety, and traffic safety fields as safety markers, significantly enhancing safety and reliability. They are also used for fiber optic deburring and polishing.

Currently, our reflective glass beads are available in specifications with refractive indices greater than N1.93 and greater than N2.2, with particle sizes ranging from 100 to 700 mesh (graded options available). The product features excellent fluidity, high sphericity, high refractive index, and comes in white and gray colors.

Reflective Principle: Reflective material products use high-refractive-index glass beads with a semi-aluminized rear surface as retroreflectors, offering exceptional reverse retroreflective performance. They can directly reflect 85% of light back to the source. The brightness generated by retroreflection ensures that drivers can clearly see pedestrians or obstacles at night or under poor visibility conditions, enhancing safety for all parties involved.

Heat Transfer Reflective Printing: Glass beads are pre-coated onto PVC film containing hot-melt adhesive to create reflective hot-melt film. This film can be cut into various texts or patterns as needed and transferred onto clothing, bags, banners, and other materials through heat pressing. The product offers excellent reflective performance and adhesion. It revolutionizes the traditional process of sewing reflective labels onto clothing, overcoming the limitations of monotonous designs and complex procedures. It not only provides reflective safety warnings but also serves as a stylish decoration, catering to the trend of personalized and fashionable apparel.
