Silicon dioxide/precipitated silica/white carbon black/sio2
Characteristic:
It is a white and colloidal micro-particle with its primary micro-particle from 5-40nm and has obvious properties such as thixotropy, reinforcing, thickening and filling etc. And is insoluble in all kinds of solvents and liquids except hydrofluoric acid and concentrated bases.
Uses:
It is used widely silicon rubber, construction sealant, coating, electron and electric, aerospace, medicine and medical material, resin processing, printing ink, pesticide and other industries.
Packing:
Packed with multi-layer paper plastic compound bag with net weight of 5kgs or 10kgs, or packed by whole plastic seal for users having special demand on water contecnt.
Store and transport: Placed in vent and dry storehouse and prevented from humid, water, pressure and throwing during transport
