BASF adds polyphenylsulfone to portfolio

Plastics supplier BASF is adding a third type of polyarylsulfone to the two existing materials Ultrason S (PSU) and Ultrason E (PESU). This new material is Ultrason P, a polyphenylsulfone (PPSU), with the first grade, Ultrason P 3010, available to customers now from the firm’s Ultrason plant in Ludwigshafen, Germany. Annual production capacity there is currently being expanded from 6000 to 12,000 tons. In addition to a transparent grade, a white and a black Ultrason P 3010 will be added to the product range.
According to the supplier, Ultrason P combines the high melting temperature of Ultrason E with the low water absorption of Ultrason S, while also displaying high chemical resistance. Significantly, it scores almost ten times higher on Charpy notched impact tests than other amorphous high-temperature materials, says BASF. It can be sterilized with high heat, withstanding up to 2000 hot-steam cycles without problems.
Likely initial applications for Ultrason P include pipe connectors and valves in plumbing, and seat and lamp covers, ventilation valves and overhead bins for carry-on baggage in aircraft. Food contact and potable water approval is being pursued.—[email protected]
