Evonik Precipitated Silica SIPERNAT

Evonik Precipitated Silica SIPERNAT series combines ultra-high BET surface area with tunable surface chemistry, offering multifunctional performance across polymer and coating systems. Its three-dimensional porous architecture enables superior anti-blocking efficiency in polyolefin films and PVC applications, while enhancing inkjet paper coatings through optimized light refraction for sharper image resolution and color vibrancy

The hydroxyl-rich surface facilitates hydrogen bonding with polar matrices, creating thixotropic networks that prevent pigment settling in coatings and improve corrosion resistance. Modified variants exhibit enhanced compatibility with silicone rubbers, simultaneously boosting tensile strength and maintaining optical clarity.
