The Kimya range of materials is being expanded with the introduction of a PPSU-S, or Polyphenylsulfone, a high-performance polymer that notably offers good shock absorption, high resistance to sterilization and low humidity absorption. It is mainly found in the automotive and aerospace industries and in plumbing applications thanks to its excellent resistance to high temperatures. Let us take a closer look at the main properties of the Kimya PPSU-S and its printing characteristics.
The PPSU-S belongs to the family of polysulfone thermoplastic polymers, which also includes materials such as PSU and PES. It is a family acknowledged for its excellent stability at high temperatures. For its part, PPSU-S offers better shock resistance than the other members of its family. It is an amorphous material with a high glass transition temperature, which offers high chemical resistance and good dimensional stability.
The properties of the Kimya PPSU-S
The following feature among the properties of our Kimya PPSU-S, which is suitable for industrial applications:
- Good mechanical resistance: stiffness &shocks
- Ease of printing
- Suitable for food contact EU 10/2011
- Autoclavable and sterilizable
- Resistant to X-rays and gamma rays
- Resistant at continuous temperatures of up to 180°C
What are the advantages of PPSU-S?
As you can see, PPSU-S is highly prized in demanding temperature environments. It also offers interesting electrical properties, whether in terms of electrical insulation but also dielectrical. It also offers strong mechanical properties with high resistance to shocks and excellent stiffness levels. Although a technical material it is easy to print, a major advantage where maximum automation of the additive manufacturing process is required.
PPSU-S calls for a 3D printer with a closed chamber capable of heating up to 120°C, a plate that may rise to at least 140°C and finally a nozzle reaching at least 360°C.
|Extrusion temperature||360-400° C|
|Print speed||15-30 mm/s|
