HDK N20 POWDER CN

HDK N20 POWDER CN is a synthetic, hydrophilic, amorphous silica powder produced via flame hydrolysis. It has a white colloidal powder appearance and high purity level. HDK N20 POWDER CN has a BET surface area ranging from 175-225 m2/g and density of approximately 40 g/l. It has a pH value between 3.8-4.3 and sieve residue of less than 0.03%. HDK N20 POWDER CN loss on drying is below 1.5% and SiO2 content is over 99.8%. Its silanol group density is 2 SiOH/nm2. HDK N20 POWDER CN is widely used as a thickening and thixotropic agent in various organic systems. It also acts as a reinforcing filler in elastomers and free flow additive in production of technical powders. HDK N20 POWDER CN provides benefits such as improved viscosity control, suspension properties and abrasion resistance. These properties make it suitable for applications in the cleaning and industrial markets.
