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
- Optimises production
- Narrow particle distribution and no fine particles

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.
