BASF SE (Ludwigshafen, Germany; www.basf.com) has started up a new production line for its high-temperature resistant thermoplastic Ultrason (polyarylsulfone) at its site in Yeosu, South Korea. With the new line, the global annual capacity for Ultrason will increase by 6,000 metric tons oer year (m.t./yr) to 24,000 m.t./yr, serving the growing market demand worldwide. The plant in Yeosu was opened in 2014 as the first Ultrason plant in Asia. Ultrason is the tradename for BASF’s product range of polyethersulfone (Ultrason E), polysulfone (Ultrason S), and polyphenylsulfone (Ultrason P).

“This capacity expansion will strengthen our competitive position and drive the global versatility of our polyarylsulfone business,” said Giorgio Greening, head of BASF’s global business unit Styrenic Foams and Specialty Polymers. “The expanded production enables us to accompany our customers’ growth at a high technical level and with the optimum product portfolio.”

BASF produces Ultrason in Ludwigshafen, Germany and in Yeosu, Korea. Both locations are designed to produce the entire product range of Ultrason S, E and P, and provide BASF with the flexibility to optimize supply capabilities to customers around the world. “With the new line we will continue to reliably serve customers and industry partners with high-quality material. Especially customers in Asia will benefit from fast response and proximity,” said Olivier Ubrich, head of global business management Specialty Polymers. “With increasing urbanization and the growing need for clean water management, Ultrason is the ideal material for filter membranes thus contributing to the desalination and purification in water treatment.”

Ultrason is widely used in the electronics, automotive and aerospace industries for the production of heat-resistant, lightweight components. The thermoplastic can withstand temperatures up to 220°C without altering its properties.
