Polyolefin

For more than 50 years, Grace has been a leading producer of polyolefin cata­lysts and additive systems. Our heritage is in polyethylene catalysts, but through a series of acquisitions, partnerships and new investments, we have rapidly expanded in the polypropylene catalyst sector. In December 2013, Grace acquired UNIPOL® PP, a proprietary gas phase polypropylene process technology for the production of a broad range of polypropylene products. Our UNIPOL® PP licensing and catalyst business also includes UNIPOL UNIPPAC™ Advanced Process Control software.
