Advanced Engineering Plastics <strong>for</strong> Elevated Temperature Range<br />
<strong>Quadrant</strong> ® PPSU<br />
Polyphenylene Sulfone [PPSU]<br />
<strong>Quadrant</strong> PPSU is a black, amorphous high per<strong>for</strong>mance thermoplastic, offering better impact strength<br />
and chemical resistance than polysulfone and polyetherimide. <strong>Quadrant</strong> PPSU also has superior hydrolysis<br />
resistance as measured by steam autoclaving cycles to failure, making it especially suited <strong>for</strong> repeated steam<br />
sterilisation applications.<br />
Main Characteristics<br />
High maximum allowable service temperature in air [180 °C continuously]<br />
Good chemical and excellent hydrolysis resistance [suitable <strong>for</strong> repeated steam sterilisation]<br />
High stiffness over a wide temperature range<br />
Very high impact strength<br />
Physiologically inert [suitable <strong>for</strong> food contact]<br />
High dimensional stability<br />
Very good resistance against high energy radiation [gamma- and X-rays]<br />
Good electrical insulating and dielectric properties<br />
Applications<br />
<strong>Quadrant</strong> PPSU is increasingly used <strong>for</strong> the manufacture of sterilisation trays, dental and surgical instrument<br />
handles, and in fl uid handling couplings and fi tting applications. Showing a very high temperature of defl ection<br />
under load [205 °C acc. to ISO 75 / Method A], <strong>Quadrant</strong> PPSU is suitable <strong>for</strong> use in electronic assembly<br />
equipment and devices that must withstand solder temperatures.<br />
<strong>Quadrant</strong> ® LSG PPSU [PPSU; <strong>for</strong> Life Science Applications; black, red, yellow, grey, brown, blue,<br />
green, rust, orange]<br />
Within its portfolio of Life Science Grade Engineering Plastic <strong>Product</strong>s - specifi cally developed <strong>for</strong> applications<br />
in the medical, pharmaceutical and biotechnology industries - <strong>Quadrant</strong> offers <strong>Quadrant</strong> LSG PPSU<br />
biocompatible engineering plastic stock shapes <strong>for</strong> machining [several colours] with certifi ed USP Class VI<br />
and/or ISO 10993 compliance [see also page 73].<br />
Tech Notes:<br />
Since unfi lled/unrein<strong>for</strong>ced amorphous thermoplastics inherently<br />
possess a low wear resistance and high coeffi cient of friction,<br />
<strong>Quadrant</strong> PPSU is not recommended <strong>for</strong> use in friction & wear<br />
applications [this also applies to Duratron ® U1000 PEI and<br />
<strong>Quadrant</strong> 1000 PSU].<br />
