Korea – BASF has started up a new production line for its high-temperature resistant thermoplastic Ultrason (polyarylsulfone) at its site in Yeosu, Korea. With the new line, the global annual capacity for the polyarylsulfone will increase by 6,000 metric tonnes to 24,000 metric tonnes, 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). Latest innovations include the optimized Ultrason Dimension, a highly filled polyethersulfone known for its extraordinary dimensional stability and excellent flow properties.

BASF produces the polyarylsulfone 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.

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, and possesses outstanding chemical stability. For example, it enables the compact design of the new headlight reflector in the Hyundai ix35, owing to its superior temperature resistance.

The high-performance material is employed in membranes for water filtration and medical devices, in hot water and food contact parts e.g. for espresso machines or microwave-proof dishes as well as in premium household appliances. It complies with the American FDA (Food and Drug Administration) and the European regulations for food contact applications. The polyarylsulfone is also used in the production of carbon fiber composite materials.
