Large surface area fumed silica in Pharma

Product DescriptionLarge surface area fumed silica in Pharma

Fumed silica is with small particle size, large surface area, porous structure and special physical and chemical properties, these speciality gives fumed silica good adsorption ability and high bio-chem stability.When added into pharmaceuticals, fumed silica acts as anti-caking agent, drug carrier and excipient to prolong drug effect.SpecificationIOTA HL4150IOTA HL4200IOTA HL4300IOTA HL4380Specific sunface area(BET), ㎡/g150±15200±20300±25380±30pH value in 4% dispersion3.9~4.53.9~4.53.7~4.53.7~4.5Loss on drying(2 hours at 105℃), %≤1.5≤2.0≤2.0≤2.5Loss on ignition(2 hours at 1000℃ based on material dried for 2 hours at 105℃), %≤2.0≤2.0≤2.5≤2.5Sieve Residue(45μm), mg/kg≤250≤250≤250≤250Silica Content(based on ignited material), %≥99.8≥99.8≥99.8≥99.8Tamped Density(based on material dried at 105℃ for 2 hours), g/dm²40~6040~6040~6040~60
