Detailed Product Description：	Floating bead (hollow ceramic beads) and physical properties of products: Shape of the superior mobility diameter hollow spherical powder (μm) 10 - 400 Color (g/cm3) 0.6-0.8 true density of non-white Bulk Density (g/cm3) 0.3-0.4 PH value of water dispersions of 6 Melting point (℃) ≥ 1400 Compressive strength (Mpa) ≥ 350 5-7 Mohs Specific resistance (Ω. CM) 1010 - 1013 Thermal diffusivity (m2 / h) 0.000903-0.0015 Thermal conductivity (W / m ? K) 0.054-0.095 Refractive index 1.54 Absorption rate g (oil) / g 0.68-0.69 Chemical composition: SiO2 AI2O3 Fe2O3 CaO TiO2 MgO K2O 50-60% 20-40% 0.5-5% 0.5-3.5% 1-4% 1-3% 0.8-2% Uses: As a filling agent can be used as heat insulation, fire retardant paint, wood products (wood, vinyl), polymers, binders, putty, glass and steel, electrical insulating materials, composite materials, refractory materials, insulation materials, building materials, are widely used in aerospace, marine, automotive and other industries. Unique properties: 1, improved rheology, reduce viscosity, reduce the product weight of hollow ceramic beads excellent liquidity, to reduce viscosity and improve the rheology and flow of ,0.3-0 .4 so that it can greatly reduce the proportion of the weight of products, reduce costs, is a new type of unsaturated resin functional filler. 2, high filling capacity, address the amount of low-adhesives, Department of hollow spherical ceramic beads, with the smallest surface area, so the adhesive filler used is less than the average. 4, the chemical stability of the hollow ceramic microspheres of aluminum silicate material and make it a strong chemical stability. 5, the fire resistance of hollow ceramic micro beads above the melting point of 1400 degrees, fire-resistant coating can be used as a good stock feed, especially for the intumescent fire retardant coating. 6, heat insulation sound insulation: thin-walled hollow sphere enclosed structure, it has a unique and heat insulation, noise and other effects, widely used in noise insulation coatings products.
