Nuplex has appointed Emery Severin as its new chief executive.
Dr Severin, who is Australian and a Rhodes Scholar, has been president of Boral Industries in the United States since 2004.
Before that, he was the executive general manager of its construction materials business in Australia.
He replaces John Hirst, who is retiring at the end of June after 43 years at the resins and chemical maker, including nine as chief executive.
Dr Severin will start at Nuplex's corporate office in Sydney in late April.
