SELECT Polyphenylsulfone (PPSU) is an amorphous high performance thermoplastic offering better impact resistance and chemical resistance than PEI. PPSU can operate in temperatures up to 180Cᵒ. PPSU has superior hydrolysis resistance when compared to other amorphous thermoplastics as measured by steam autoclaving cycles, it has virtually unlimited steam sterilizability. It also resists common acids and bases over a broad temperature range. Applications are; Aerospace, Aircraft, Automotive, Dental, Medical, Surgical instruments. The PPSU filament is based on the technology of Solvay.
The PrimaCreator PPSU Filament has unique properties because it does not come into contact with water during the production process and is directly packaged in a vacuum packaging. These properties make the PrimaCreator PPSU Filament particularly suitable for usage in FDM and FFF 3D printers. The material has an excellent adhesion between layers which results in great improvement of the impact resistance, strength, durability and the printing process.
The PPSU Filament produced by PrimaCreator meets the ISO10993 for medical applications and meets the European regulations EC No. 1935/2004, EC No. 2023/2006 and EC No. 10/2011 concerning plastic materials and articles coming into contact with food and is also compliant with the FDA (Food and Drug Administration) for food contact. The colorants used by PrimaCreator to colour the Filament also meet these European regulations.
To make a successful PPSU print there are a few things to keep in mind.
The printer must have the performance to meet the PPSU filament and it should be printed with a nozzle temperature of 360 - 400°C. The heat bed should be set to 140°C or higher, and a heated chamber is important to have. It´s also very important to make sure that the printer is placed in a room where there´s hardly any draft and temperature fluctuations.
PPSU is best printed on a PEI sheet at a printing speed of 15-30 mm/s.
