15 August 2007 BASF has added a polyphenylsulphone to its Ultrason family of high performance amorphous engineering polymers. The latest addition is Ultrason P, which forms a third component of the range and is being made on the company s Ludwigshafen plant, which is currently being doubled in size to 12 000tpa.
Ultrason P combines the high melting temperature of Ultrason E (polyethersulphone) with the low water absorption properties of Ultrason S (polysulphone) and is particularly good in terms of notched impact resistance, a common weakness of the amorphous polymers.
In fact, BASF reports, Ultrason P has a Charpy notched impact strength almost ten times greater than other high temperature amorphous materials.
Typical applications for which the property range renders it suitable include pipe connectors and valves where 40 year warranties are not unusual, as well as in the aerospace sector. The ability to withstand sterilisation and cleansers used in the dairy industry make this another potential application, according to BASF.
The first grade of BASF s new material Ultrason P 3010 is already available.
A polyphenylsulphone is supplied by Solvay Advanced Polymers under the Radel R name.
