Polyolefin Supports

High performance silica catalysts & supports designed to give exceptional performance within the polyolefin market

PQ silica supports are used in the production of chrome, Ziegler-Natta and single site catalysts that are subsequently used to manufacture polyethylene, polypropylene and other polymers.


In the production of polymers, the surface area, pore volume, and pore diameter of the catalyst support strongly influences the polymerization characteristics (e.g. activity) and final polymer properties (e.g. melt index and environmental stress crack resistance). Accurate control of the particle size distribution is also extremely important since the growing polymer replicates the shape and size distribution of the silica catalyst particles.
