SustaPEEK MG green GN


Our premium material especially for medical devices

SustaPEEK MG was developed for the demanding requirements of the healthcare industry in particular medical devices. As a material of highest purity with exceptional resistance to sterilisation, it is e.g. ideal for surgical instruments. Thanks to its very high strength and rigidity, SustaPEEK MG ensures reliable performance in all applications. It retains its shape and property profile even under extreme conditions. With its excellent temperature stability of up to 250 °C in continuous use, it offers reliable performance.



  • High purity
  • Very good sterilisation resistance
  • very high strength and rigidity
  • ISO 10993-5 tested on semi-finished product
  • high-temperature stable up to 250°C in continuous operation
  • Chemical resistance


Application Examples

Breast biopsy unit

The breast biopsy unit is precision machined to meet tight tolerances according to the customer's drawings. It offers excellent cleaning and sterilisation procedures as well as biocompatibility in accordance with DIN EN ISO 10993-5 and is supplied as an assembly group made of SustaPEEK MG material.

Handle for surgical instruments

Our challenge was to find a material that can be sterilised, offers a high-quality feel and surface quality, and at the same time can be manufactured with tight tolerances. SustaPEEK MG was chosen due to its outstanding properties. It offers good stability during production, which is crucial for manufacturing complex components and maintaining tight tolerances. It is also heat dissipative and has good thermal properties and excellent chemical resistance.
