BASIC INFO
Glass beads Granules are a crucial component of road marking materials, especially thermoplastic and paint-based markings. They enhance the visibility and retro-reflectivity of road markings, making them more effective in guiding drivers, particularly at night or in low-light conditions.

Materials:
The raw materials of glass beads are divided into heavy metal glass, recycled glass and pure glass.
- Heavy Metal Glass: The price is the most economical. The reflective effect is very good. However, the heavy metal of the glass will pollute the environment a little.
- Recycled Glass: It is very competitive in price, with the characteristics of good reflection and less damage to the environment, which is widely used in the world.
- Pure Glass: It does not have no any pollution to the environment even though the price is the most expensive. The reflection is very good.
Advantages:
- The glass beads made of the soda-lime silica glass has the good chemical stability, certain mechanical intensity and hardness, free of dark spots and other impurities.
- Does not cause dimensional change to the base material
- Soda Lime glass does not release toxins (no free silica), will not contaminate or leave residue on work pieces, environmentally friendlier than chemical treatments
- Leave even, spherical impressions on blasted part surface
- Low breakdown rate, Lower disposal & maintenance costs
- Suitable for pressure, suction, wet and dry blasting equipment
