High Performance Polymers

Ultrafuse® PPSU


General Information

Outstanding thermal stability, good chemical resistance and high strength are the key features of Ultrafuse® PPSU. Parts produced by fused filament fabrication show often mechanical limitations in z-direction – the good layer adhesion of Ultrafuse® PPSU leads to balanced flexural strength properties between z- and x-direction.
Ultrafuse® PPSU can be used for functional applications which require a high mechanical strength as well as a high heat distortion temperature – properties, where existing 3D printing materials often show limitations.
