PPSU 1000 - PEI 1000 - PSU 1000

These unreinforced amorphous materials have a lot of features in common and all three offer a combination of excellent mechanical, thermal and electrical properties.

Main characteristics

• High maximum allowable service temperatures in air (180°C, 170°C and 150°C continuously for PPSU 1000, PEI 1000 and PSU 1000 respectively
• High mechanical strength and stiffness over a wide temperature range
• Excellent hydrolysis resistance (suitable for repeated steam sterilisation)
• Tough, even at low temperatures
• Physiologically inert (suitable for food contact)
• Very good dimensional stability
• Translucent, non-optical quality (except for PPSU 1000 which is black)
• Very good resistance against high energy radiation (gamma- and X- rays)
• Good electrical insulating and dielectric properties

Applications

Sighting arm and positioning sight, clamps, cleaning equipment inserts.

PPSU 1000 (black) (PPSU)

PPSU 1000 stock shapes are produced from RADEL® R resin. This material offers a better impact strength and chemical resistance than PSU 1000 and PEI 1000. PPSU 1000 also has superior hydrolysis resistance as measured by steam autoclaving cycles to failure. In fact, this material has virtually unlimited steam sterilisability. This factor makes it an excellent choice for medical devices which are subjected to repeated steam autoclaving.

Additionally, the raw material used for the production of PPSU 1000 stock shapes is USP Class VI compliant making it a very popular material for medical and pharmaceutical industries (e.g. sterilisation trays, dental and surgical instrument handles, orthopaedic implant trials and fluid handling coupling and fitting applications).

Delivery Programme: rod 5 - 150 mm, plate 10 - 50 mm

PEI 1000 natural (amber, translucent) (PEI)

PEI 1000 stock shapes are produced from ULTEM® resin. This advanced polymer features a combination of outstanding thermal, mechanical and electrical properties, together with very low flammability and low levels of smoke evolution during combustion making it extremely suitable for electrical / electronic insulators and a variety of structural components requiring high strength and rigidity at elevated temperatures. Thanks to the good hydrolysis resistance of polyetherimide and because the raw material used for the production of PEI 1000 stock shapes is USP Class VI compliant, medical devices and analytical instrumentation are obviously important application fields.

PSU 1000 natural (yellow, translucent) (PSU)

PSU 1000 stock shapes are produced from non-UV-stabilised polysulphone resin. It offers very good radiation stability, low ionic impurity levels and good chemical and hydrolysis resistance. Compared to PEI 1000, it has a lower property profile, often replacing polycarbonate whenever higher temperature resistance and improved chemical resistance are required. PSU 1000 is commonly used in food processing equipment (milk machines, pumps, valves, filtration plates, heat exchangers) and for medical components subject to repeated cleaning and sterilisation.

Delivery Programme: rod 5 - 150 mm, plate 10 - 50 mm
