BASF will set up an additional production line for Ultrason polyarylsulfone at its site in Yeosu, Korea. The new line will start up at the end of 2017, adding a production capacity of 6,000 metric tons per year and bringing BASF’s total annual capacity of Ultrason to 24,000 metric tons.

BASF produces Ultrason in Ludwigshafen, Germany and in Yeosu, Korea. Following the start-up of the plant in Korea in 2014, the company continues its commitment to supplying markets globally with high performance thermoplastics. Both locations are designed to produce the entire product range and provide BASF with the flexibility to optimize supply capabilities to customers around the world.

Ultrason is the trade name for BASF’s product range of polyethersulfone (Ultrason E), polysulfone (Ultrason S), and polyphenylsulfone (Ultrason P).

Ultrason is used in applications in the consumer, electronics, automotive and aerospace industries. Common applications include heat-resistant, lightweight components in, for example, household appliances or fittings for drinking water pipes. The market growth of polyarylsulfones is strongest for filtration membranes in technical and healthcare applications – especially in Asia’s emerging markets.
