High-Purity Silicas for Zeolite Catalyst Applications

For more than five decades, PPG HI-SIL^® silicas have been specified by zeolite catalyst manufacturers and refinery operators worldwide to facilitate the most difficult reactions and separations in the industry.
 
That tradition continues today with Hi-Sil 250, a high-purity, sulfate-deficient engineered silica that is ideally suited for the manufacture of high-silica zeolites specified in fluid catalytic cracking (FCC), hydrocracking, custom and specialty catalyst applications.
 
Our ability to precisely select and control particle size, surface area and pore structure of both Hi-Sil 250 and 915 silicas provide the desired catalyst support structure required for polymer synthesis applications. 
 
Available for global delivery, Hi-Sil silicas provide chemists with a trusted solution to meet the stringent requirements of today’s catalyst market.
