Quick Details
Specifications
cenosphere is one of the best filling materials for paint, printing ink, carbon, fiber, GRP, leatheroid, rubber, plastic, petroleum field(anchoring, pipeline, anticorrosion and warm keeping), and so on.
Cenospheres are light are light gray or off-white, light, inert and nonmetallic hollow ceramic spheres in the range from 10um to 850um.With N2 or CO2 inside and over 95% spheres, the material has excellent fluidity as well as sound electric and heat insulation.
