White carbon black microbeads
Silica black is a general term for white powdered X-ray amorphous silicic acid and silicate products, mainly referring to precipitated silica, fumed silica and ultra-fine silica gel, and also includes powdered synthetic aluminum silicate and calcium silicate. Soluble in caustic soda and hydrofluoric acid, insoluble in water, solvents and acids (except hydrofluoric acid). High temperature resistance, non-flammable, tasteless, odorless, with good electrical insulation.
| Property/Specification | Value/Description |

| Oil Absorption Value | ≥2.0-2.5 |
| Heating Loss (105℃) | ≤5.0% |
| Ignition Loss (1000℃) | ≤7.0% |
| Water Soluble Matter | ≤2.5% |
| Total Iron Content | ≤1000 ppm |
| Residual on Sieve (45μm) | ≤0.5% |
| 300% Modulus | ≥5.5 MPa |
| Tensile Strength | ≤19.0 MPa (note: typically tensile strength would be a value indicating resistance to breaking, so ≤ might be a typo or specific context; here retained as per original) |
| Elongation at Break | ≥550% |
| Execution Standard | HG/T3061-2009 |
