It is a white, submicron-sized powder of great purity and a surface area of 20 to 50 m2/g. RS-50 is effective as a thixotropic rheology control and thickening agent in many polymer systems, such as unsaturated polyesters, adhesives, sealants, coatings, printing inks, etc. It can be used as active strengthening filler in silicone-elastomers and elastomers. Pyrogenic Silica RS-50 has a specific gravity of 2.2, a bulk density of 23 to 25 lb/ft3 vibrated, oil absorption of 65 g/100g, a pH of 6.0 (4% dispersion in water), a refractive index of 1.46, and a softening temperature of ~1600 °C. 收起 |
