HJSIL® Fumed silica

HJSIL® Fumed silica

 


CHARACTERISTIC


HJSIL® Fumed silica is a kind of high purity white colloidal powder, including hydrophilic & hydrophobic types.

  • Small particle size:7 ~ 40 nm.

  • Bigger surface area:150~380.

  • More activate surface

APPLICATION


Here are the main applications which fumed silica could be used into. Exact grade is up to final customer's formulation request.

For coatings & paints: thickening, rheopexy, antisettling, dispersing, fluidity, increase anti-corrosive property.

For printing inks: thickening, rheopexy, anti-settling, water balance, increase brightness and contrast.

For HTV silicone rubber: reinforcement, increase dielectric property.

For sealants & adhesives: Thickening, rheopexy, increase adhesive force.

For UPR: Thickening,increase thixtropy property.

For Heat insulation materials: heat insulation ( VIP: vacuum insulation panels for construction, refrigerator, coolers of transport blood, medicine, etc---shrink the panel dimension volume while increase the thermal insulation property).

 

For Gel battery: thickening, rheopexy, fixing electrolytes.

For Super Absorbent polyesters (SAP): used in baby diapers or water-retaining agent for agriculture.

For Defoamer: Thickening,anti-settling,adsorption.

For Cable filling paste: thickening, increase thixotropy property.

For Casting: Thickening, anti-sagging, increase glossiness.
