Product Details
LK Series Silica1. Precipitated Hydraed Silica, molecular formula is: SiO2·nH2O; appearance is white granular of powder, product code is LK955-1, LK955-2, LK965, LK975, LK985.
2. Property
Physical Property: LK series silica are produced by precipitation way, production parameters are controlled automatically, through which different types' silica can be produced accurately. It also can be produced according to demand. LK series silica possess density 0.192-0.320, fusion point 1750οC, refraction index 1.46(except LK985), hollowness, with large active surface area. It has good dispersancy in green rubber with property of quick mixing and high optensity.
Chemical property: silica belongs qinert material, which possesses high insulation and indissolves in high temperature. It is insolvable in water, acid and all kinds of solvent. But it is solvable in caustic soda and hydrofluoric acid.
