· Abundant internal pores and high specific surface area deliver superior adsorption and moisture absorption performance. They keep active pharmaceutical ingredients dry, prevents degradation and boost formulation stability.
· The large specific surface area—typically exceeding 200 m²/g—and high surface activity enable significant adsorption capabilities for both hydrophilic and hydrophobic compounds.
· Its fine particle size allows silica microparticles to evenly intersperse among drug powders. This spacer effect reduces inter-particle friction, improves powder flowability, and functions as glidant, lubricant and anti-sticking agent. It ensures smooth tableting and avoids tablet capping or lamination defects.
· Controllable particle size distribution achieves homogeneous mixing with APIs and guarantees consistent content uniformity of finished drugs.
· Rich hydrophilic groups on the particle surface absorb ambient moisture to form conductive films and facilitate proton transfer, lowering surface resistance and delivering reliable antistatic performance.
