Indorama Ventures PTA Montreal L.P. (IVPTA)

Acquired in 2015

Entreprise Indorama PTA Montreal, formerly CEPSA Chimie Montreal (CQM) and initially Interquisa Canada, was created in 2000 from a partnership between Société générale de financement (SGF) and CEPSA (Spain). Established in the heart of the industrial zone of eastern Montreal, the plant has been in operation since 2003. The proximity of several petrochemical plants allows synergy and better collaboration between the different plants that make up the polyester chain. The plant has a production capacity of 600,000 metric tons per year. It produces purified terephthalic acid (PTA), a raw material used in the production of polyester and other synthetic materials. The plant employs more than 140 skilled workers, engineers, technologists and technicians. It was acquired by Indorama Ventures in 2015.
