Product description: A high purity and white spherical powder. It has high spheroidization rate with uniform particle size (3 - 12μm), low dielectric constant, low coefficient of linear expansion, high filling ratio and high fluidity. It is an amorphous mesoporous product synthesized by precipitation.
☆Spherical white powder, high spheroidization rate, no smell.
☆Strong fluidity, high smoothness and low stress.
☆99.9% high purity silica, less content of metal impurity and magnetic ion.
☆Porous structure, high porosity, high pore volume, small specific surface area, excellent adsorption performance and obvious sustained-release effect.
☆Stable chemical properties, amorphous structure, non-radioactive amorphous element, non-toxic and tasteless, high temperature resistance, chemical corrosion resistance, acid and alkali resistance, stable weather resistance.
☆Uniform and narrow-distributed particle size (0.5 - 20μm).
☆Low dielectric constant 3.88/k, low loss 0.0002 (1MHz), low expansion 0.5 × 10-6, heat conduction 1.1w/k. M.
☆The refractive index is about 1.5, which is close to the refractive index 1.4-1.5 of most resins. It is used in rubber and plastic, coating, adhesive, LED light diffusion lampshade and other products with high light transmittance.
☆Mohs hardness 6, impact resistance, scratch resistance, wear resistance.
☆Various surface modification options, superior dispersion performance.
☆Spherical structure, porous sphere and easy to scatter, absorb light, obvious matting effect.
