Vitro Minerals Pyrogenic Silica RS-50 is a100% recycled synthetic, hydrophilic, fully X-ray amorphous silica, produced via flame hydrolysis. It is a white, submicron-sized powder of high purity and a surface area of 20-50 m/g. The primary particles, sized between 60 and 300 nm (0.06-0.3 um), are spherical and form loosely agglomerated micro-clusters up to about 3 um.

- HIGHLIGHTS
RS-50 is effective as a thickening and thixotropic rheology control agent in many polymer systems, such as adhesives, coatings, sealants, printing inks, unsaturated polyesters, cosmetics, etc. It can be used as an active reinforcing filler in elastomers and silicone-elastomers. RS-50 is also effective as a flow aid additive in the production of industrial mineral powders.
