Hydrophilic Fumed Silica Hl-200 Hot Selling Magnetic Ultrafine Silica to Improve The Waterproof Performance of Plastics

Its appearance is white powder. Native particle size ranges from 5nm-40nm, with significant functions of thixotropy, reinforcing, thickening and filling. Therefore, it is widely used in the industries of rubber, sealant, plastic, resin, paint, printing ink, papermaking, medicine, cosmetics, food etc.

HL-200 is hydrophilic fumed silica with specific surface area around 200 m2/g.

Properties:* Reinforcing filler in elastomers
* Anti-settling, anti-sagging and thickening agent
* Rheology control and thixotropic agent
* Free flow aid and anti-caking aid for powders
* High tear resistance
