Technical Data Sheet
Catalyst Bed Support Media: Alumina/Silica Spheres
Products to these specifications are manufactured from very high quality chemical-porcelain clay materials, which
has excellent stability, high mechanical strength, and resistance to thermal shock. This makes them an ideal choice
for many types of catalyst support materials.
