Features:

1. Glass bead is a kind of hollow glass sphere with small size, which belongs to inorganic non-metallic material. 

2. Light specific gravity and large volume. 

3. Organic modified (lipophilic) surface. 

4. High dispersion and good liquidity. 

5. Low heat insulation, sound insulation, insulation and water absorption. 

6. Low oil absorption rate.

Characteristic:

1. Low price; 

2. Enhance the toughness of plastics without reducing its own stiffness; 

3. High melting point, which can improve the flame retardant performance and Vicat softening point of the filler;
4. Good electrical insulation, which can be used for filling high insulating polymers;
5. Increase the fluidity of fillers, increase the processing performance of plastics, improve the surface leveling of engineering plastics, and solve the surface problem of glass fiber reinforcement;
6. It can effectively reduce the shrinkage of the filler;
7. Compared with engineering plastics filled with glass fiber, calcium carbonate and talc powder, the real density of 1.78g/cm3 (bulk density of 1.12g / cm3) can significantly reduce weight;
8. Corrosion resistance;
