The performance products division of Huntsman Corporation is going ahead with the engineering design for a 40,000-ton capacity expansion program at its world-scale polyetheramine facility in Singapore. Huntsman plans to invest more than $70 million at its Jurong Island plant in a move that will more than double the site’s manufacturing capabilities, help satisfy increasing global demand for polyetheramines and strengthen the company’s position in this technology. Polyetheramines are typically employed in epoxy coatings or in additives that enhance the performance of fuels, concrete and pesticides.
