Glass bead
The coated glass bead have been treated with high quality organic materials on their surface, thus bearing better features in quality. Our company has developed this unique product after absorbing advanced technology from foreign countries and it has the following advantageous features:
A The contrary reflexible of the micro glass beads maintains since we select the materials which are similar to the nature of micro glass beads.
B In rainy and wet weather, ordinary glass beads would be surrounded by water and result in th low reflection rate. However, the micro beads with coated can maintain the reflection effect to a great extent.
C Ordinary glass beads would pile up in the sprayer after absorbing water. However, micro beads with coated would not so, thus increasing the working efficiency.
D since micro beads with coated contain special adhesives, thus improving the integrity between the micro beads and the paints.
E Can prevent sinking of micro beads to the bottom of paints.
F after the treatment of coated thus absorbing less dust from air.
Products according to international standard include: BS6088, EN1423&EN1424, AASHTO, JIS R3301, AS/NZS 2009:2002, KS, etc.
Glass bead for jetting has the features of chemical stability, high mechanical intensity and hardness. They can be jetted onto the object surface with compressed air and can be used on compress glass, rubber, plastic, moulds with metal casting or compressing. The jetting balls would help reduce elasticity of the surface materials and increase wearing capacity.
Glass Bead for grinding ,With the advantages of smooth surface, even size, high hardness, wearable and stable, widely used as disperser, grinding media and filler materials in day, paint, ink and chemical industry.

Package
1.Using double-deck package, the inner is polythene film and its thickness is not less than 0.5mm, the outer is plastic woven bag to prevent leak or damp. The net weight of each bag is 25+0.2kg.
2.Using double-deck package, the inner is polythene fim and its thickness is not less than 0.5mm, the outer is plastic woven bag to prevent leak or damp. The net weight of each is 1000+8kg.
3.According to clients' requirement.
1.Improve the road marking line contrary reflection function. When driving at night, the lamp shines on the marking line with glass bead in it, the ray of lamp is reflected back parallely. So the driver can look at the road clearly and drive safely at night.
2. Products according to international standard include: jt/t 446-2001, english bs6008, korean, ks and american aashto etc.
3. You can choose different size glass bead between 50um-1180um according to different function.
25kg/bags, 40bags/pallet, using double-deck package, the inner is polythene film and its thickness is not less than 0.5mm, the outer is plastic woven bag to prevent leak or damp.The net weight of each bag is 25f+0.2kg.
Glass beads are made of broken glass, flat glass and other raw materials by high temperature melting bead processing. Low thermal conductivity, high strength, good chemical stability, and the texture of glass beads themselves, glass beads instead of plastic raw materials are widely used in filling, such as gravity blanket filling, compression filling, medical filling, weighted blanket filling, toy filling and so on.
Our products win the good reputation in the international market for the superior quality and competitive price.
Reflective glass beads for road marking is one of most popular products, all types are available in our company, such as BS6088A/B, EN1423 /EN1424, AASHTO M247 type1/2/3, KSL2521 No.1/2, JIS R3301, etc. And also we can produce the glass beads according to the client's specification.
