TECAFIL PPSU filaments are based on the amorphous base polymer polyphenylene sulfone. The PPSU filament is particularly resistant to hydrolysis and is suitable for repeated hot steam sterilisation. PPSU filament is considered heat resistant due to its high temperature resistance of up to 220°C (glass transition temperature). It also has low moisture absorption and high dimensional stability.
These properties make PPSU filaments ideal for use in demanding applications such as medical technology.
In addition to the universally applicable TECAFIL PPSU natural, we offer PPSU filaments explicitly manufactured for the medical industry. With our medical grade filament portfolio, we offer biocompatible filaments that have been produced according to ISO 13485 and tested resp. evaluated for biocompatibility according to standard ISO 10993-1, -4, -5, -18 and meet the specified requirements for contact of up to 24 hours with skin and tissue and, if applicable, indirect contact with blood. TECAFIL PPSU MT is also available in x-ray detectable variants and different colours.
