Univation was initially formed in 1997 and is a joint venture between ExxonMobil Chemical Company and The Dow Chemical Company.

Over thirty years of PE process innovation stand behind Univation Technologies. In the late 1960s, a method using chromium and Ziegler-Natta catalysts in the UNIPOL™ PE Process gas-phase process was invented to produce high-density PE. In the late 1970s, that knowledge extended to the use of Ziegler-Nata catalysts to make linear or low-density PE.

In the mid 1990s, ExxonMobil Chemical Company developed the first commercial single-site metallocene catalysts for use in the UNIPOL™ PE Process. Under Univation stewardship, numerous catalyst and process enhancements have taken place. These include the development of bimodal catalysts, enabling the production of bimodal film resins in a single reactor.
