SUNSPERA®, one of the more recent products launched, is used as a catalyst support in the manufacture of polyethylene and polypropylene, playing a more important role than simply that of a carrier for a catalyst compound. The properties of the silica gel have a significant effect on both the polymerisation process and the properties of the finished polymer.
The pore structure, spherical shape and particle distribution of SUNSPERA® for catalyst support are precisely defined. Using SUNSPERA® gives improved finished polymer resin by increasing the bulk density and also ensures enhanced productivity.
Bare Silica before Polymerisation
Precisely designed pore structure, spherical shapes and size distribution
Improved morphology of finished polymers
Narrow particle distribution and no fine particles
Average particle size (μm)
SUNSPERA® is available in average particle diameters from 3µm to 100µm to suit any application. Surface areas are available from 40 – 800m2/g. The ability to select the sphere size, pore size and spherical structure of this fine silica product makes it possible to provide long-lasting, physicochemical-specific characteristics to specific media.
