Quadrant ® PPSU<br />
Quadrant ® 1000 PSU<br />
Properties of Quadrant ® PPSU (polyphenylsulphone)<br />
Material density:<br />
1.29 g/cm 3<br />
Service temperature:<br />
+180/210 °C (20.000 hours/temporary)<br />
Temporary = only a few hours, where no or only low loads may<br />
occur<br />
Non-reinforced amorphous thermoplastic with superior<br />
mechanical, thermal and electrical properties.<br />
Main properties of Quadrant ® 1000 PPSU:<br />
• High upper continuous service temperature limit in air 180 °C<br />
• High mechanical strength over a wide temperature range<br />
• Excellent hydrolysis resistance (suitable for repeated steam<br />
sterilisation)<br />
• High toughness even at low temperatures<br />
• High dimensional stability<br />
• Very good resistance to high-energy radiation<br />
(gamma and X rays)<br />
• Good electrical and dielectric behaviour<br />
• Physiologically safe (suitable for contact with foodstuffs)<br />

Main properties of Quadrant ® 1000 PSU:<br />
• High upper continuous service temperature limit in air 150 °C<br />
• High mechanical strength and rigidity over a wide temperature<br />
range<br />
• Excellent hydrolysis resistance (suitable for repeated steam<br />
sterilisation)<br />
• Very high dimensional stability<br />
• Good resistance to high-energy radiation (gamma and X rays)<br />
• Good electrical and dielectric behaviour<br />
• Physiologically safe (suitable for contact with foodstuffs)<br />
• Translucent, non-optical grade<br />
• Good hydrolysis resistance<br />
Comment:<br />
All amorphous thermoplastics are prone to stress cracking. Liquid<br />
coolants with an oil-soluble base must not be used during cutting.<br />
Preference should be given to water or compressed air for these<br />
materials.<br />
Grade: Quadrant ® PPSU colour black<br />
Semi-finished products are made from RADEL ® . This material<br />
offers better impact strength and chemical resistance than PEI<br />
1000 and Quadrant ® PSU and also provides outstanding resistance<br />
to hydrolysis. This material can actually be steam sterilised to an<br />
almost unlimited extent.<br />
Application: Quadrant ® PPSU<br />
The material properties described mean the material is perfect<br />
for use in the medical field for devices that have to be steam<br />
sterilised over and over again. Furthermore, the raw material used<br />
to manufacture Quadrant ® PPSU semi-finished products meets the<br />
requirements of Class VI of the USP standard (medical engineering<br />
and pharmaceutical industries).<br />

Comment:<br />
All amorphous thermoplastics are prone to stress cracking. Liquid<br />
coolants with an oil-soluble base must not be used during cutting.<br />
Preference should be given to water or compressed air for these<br />
materials. Quadrant ® 1000 PSU is not UV-resistant.<br />
Grade: Quadrant ® 1000 PSU colour natural (yellow, transparent)<br />
This material offers very good radiation resistance, good ionic<br />
cleanliness and superior chemical and hydrolysis resistance.<br />
Compared to PEI 1000, Quadrant ® 1000 PSU has a somewhat<br />
lower property profile and is often used as a substitute for<br />
polycarbonate if a higher temperature resistance, better chemical<br />
resistance and the ability to steam sterilise are required.<br />
Application: Quadrant ® 1000 PSU<br />
Areas of the food processing industry – such as milking machines,<br />
pumps, valves, filter plates and heat exchangers, as well as<br />
for medical engineering components which need to be cleaned<br />
and sterilised repeatedly<br />
