Detailed Selling Lead DescriptionBrand: CHINA WINS
Model: SiO2·nH2O
Min. Order: 100
Name : White Carbon Black
Molecular Formula : SiO2 ?nH2O
Uses :Used as reinforcing filler of natural rubber and synthetic rubber, filler of synthetic resin, densifier (bodying-agent) of printing ink, anti-settle agent of dyestuff for coating, flatting agent, soft polish for vehicles and metals and anti-settle agent of emulsion agent, as well as carrier of pesticide and filler of light newsprint paper.
Technical parameter:
SiO2 ≥91％
Loss on heating ≤(4-8)%
loss on ignition ≤ 7%
PH value 6.5-7.5
Screen Residues through 45um mesh ≤ 0.5％
Fe ≤ 500 mg/kg
Physicochemical Properties: White amorphous powder, light in weight, original particle size is below 0.3um. Relative density is 2.319-2.653, melting point 1750℃. After moisture absorption, polymerizing fine particles will be formed. It is very high in insulation, soluble in caustic soda and hydrofluoric acid, insoluble in other acids and various solvents. It is not discomposed under high temperature and has water absorption. It shows chemical inertia for base, active composition and additives. And it has better compatibility to vitamins, hormone, fluoride, antibiotics, enzyme preparation and many common active compositions in cosmetics. Due to its porosity and big specific surface area, it has higher ability of disperse in raw rubber. It will show high reinforcement if filled into rubber.
Packaging: 25KG/Bag, plastic woven bag lined with polyethylene plastic bag
