parameter: Particle Size(um):75-150 Ratio of sphere(%):>85 Average Bulk Density(g/cm3):0.30-0.60 Melting Temperature(℃):1200-1750 Dielectric constant(ε):2.3-2.4 Oil absorption g(oil)/100g:16-18 Hardness (Mohs scale):5-7 Lost in Ignition :(%):<1 Thermal Conductivity W/(m稫):0.07-0.12 Compressive Strength(Kg/cm2):1000-6000 Volume resistance(Ω穋m):1.5 x 1010 Specific surface area(m2/g):1.9(3um) Major Advantages: ◆Resistant to corrosion, stable in various types of organic solvents, acid and alkali solvents and nonsusceptible to chemical reaction. ◆Improves the flowability and processibility of filled materials. ◆Low oil absorption enables Cenosphere to effectively reduce the contraction rate of filled materials. ◆Excellent electrical insulation and applicability to high-insulation polymers as filler. ◆Great difference in average bulk density for Cenosphere of various types and particle sizes, available for different applications. 0.45g/cm3 unit weight minimum. Greatly reduces the weight and cost of filled products. ◆Excellent high-temperature behavior, high melting point, nondecomposable and nondeformable under high temperature. Improves fire retardancy and high-temperature behavior of filled products.
