PolySulphone (ULTRASON S® UDEL®)

Marketed under the trade names of Ultrason® S from BASF and Udel® from Amoco Performance Products, PSU remains stable, resisting creep and deformation under continuous load and elevated temperatures.

Also having a high tensile strength and, as temperatures increase, flexural modulus remains high.

High thermal stability combined with X-ray transparency, resistance to hydrolysis and autocalvable nature, makes this a candidate for medical applications.

Resistance to microwaves (2.45 GHz range) even at high temperatures makes it suitable for cooking utensils or medical parts.

P.S.U is covered by MIL-P-46120, FDA, NSF and is certified for applications in the dairy equipment according to 3A- Sanitary Standards. Pharmacopeia P VI grades available on request.

PSU can be characterised by the following properties:

• Excellent chemical resistance
• Steam sterilizable up 30,000 times without any affect on mechanical properties
• Continuous service temperature in steam to +135C
• Good mechancal strength and electrical properties
• Good clarity


Only on special request. Minimum Order Quantities.
