The DuPont Co. says it will expand its global titanium dioxide production by about 350,000 metric tons to help meet increasing demand for the widely used pigment.
The expansion announced Wednesday includes a new production line at the company's Altamira, Mexico site, and improvements at other production facilities around the world.
The company said it will invest $500 million in a new production line at the Altamira site that would be completed by the end of 2014 and provide about 200,000 metric tons of new capacity per year.
Other upgrades at the Altamira site and at facilities in Mississippi, Tennessee, Delaware and Taiwan will yield an additional 150,000 metric tons of capacity.
Titanium dioxide is a whitening pigment used in products ranging from automotive and house paint to toothpaste.
