Cenosphere or Hollow ceramic microspheres paint additives
Cenosphere are lightweight, inert, hollow, nonmetallic spherical materials, composed largely of silica (SiO2) and alumna (Al2O3) compositions of Cenospheres are similar with glass and ceramic.
1.Those hollow glass particles have also been called hollow ceramic spheres and micro spheres.
3.Due to their unique combination of spherical shape, high strength in compressing, good sound and thermal insulation, Cenospheres are utilized as a high performance filler material, that can replace other mineral filler.
Cenospheres are extremely free flowing powder composed of light shelled, hollow, small spheres. They have ultra low density, nonpoisonous, corrosion-resisting, thermal stable, high particles, strength, good insulating, sound isolating, low water absorption low thermal conductivity that are extensively used in the rubber equipment of glass fiber reinforced plastic, polyester, plastic as filler.
Cenospheres also are utilized for coating, paint and oil industry. Cenospheres are not only can reduce the weight of end products and cost but also increase the strength.
Hollow Sphere, 15 – 300 μm in diameter and are spherical, hollow. Due to the good flow ability, lightweight, Cenosphere can be used as filler materials.
Low Bulk Densities. Cenospheres bulk densities are 0.35 – 0.45 g/ cm3, provide up to four times the bulking capacity of normal fillers. They can greatly reduce cost of products, resin demand and weight of the end products.
Cenospheres are 300% less expensive than man-made hollow glass sphere.
High Compressive Strength. The shell thickness of Cenosphere is about 10% of the radius. Their inside of the shell consist mainly of CO2 and N2. Due to the above spherical shape, Cenospheres can produce higher compressive strength.
Low Thermal Conductivity.
Good Sound Isolating
Good Insulation. Cenospheres conduct very little electricity and are ideal insulators used for making many electricity device.
Stability in Chemicals. The alumino-sillicate shell is resistant to water, any organic solvents, acids or weak alkalis. Like most glasses, Cenospheres are not resistant to strong alkalis.
Thermal Stability. Their thermal stability in temperature exceeding 1450C.
Resistant to Water.
Low Shrinkage. Cenospheres are one of the few products in the filler industry today that can meet the requirements for low shrinkage. Cenospheres can reduce shrinkage when utilized in high volume loadings.
