cenosphere is one of the best filling materials for paint, printing ink, carbon, fiber, GRP, leatheroid, rubber, plastic, petro
manufacturing cenosphere in various sizes between 10µm to 850µm and has established an annual production capacity of 5000MTS. Due to its unique combination of hollow spherical shape, light weight, high melting point, high compression strength, good sound electrical and thermal insulation, 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 10µm to 850µm.With N2 or CO2 inside and over 95% spheres, the material has excellent fluidity as well as sound electric and heat insulation.
