Ultrafuse PPSU
Date / Revised: 26.03.2020

Version No.: 1.5

General information
Components
BASF Polyphenylsulfone (PPSU) based filament for Fused Filament Fabrication.

Product Description
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 ahigh heat distortion temperature – properties, where existing 3D printing materials often show limitations.

Delivery form and warehousing
Ultrafuse PPSU filament should be stored at 15 - 25°C in its originally sealed package in a clean and dryenvironment. If the recommended storage conditions are observed the products will have a minimum shelf lifeof 12 months.

For your information
Ultrafuse PPSU comes in its natural yellow/brown color. Chemical properties (e.g. resistance against particularsubstances) and tolerance for solvents can be made available if these factors are relevant for a specificapplication. Generally, these properties correspond to publicly available data on polysulfones. This material is
not FDA conform.

Product safety
Recommended: Process materials in a well ventilated room, or use professional extraction systems. For furtherand more detailed information please consult the corresponding material safety data sheets.

Drying Recommendations
Drying recommendations toensure printability

Spools can be dried in a vacuum dryer at 125 °C / 257 °F for 8 hours andshould be stored in a closed box during printing. High moisture content isvisible by bubbles in the material after the melting process.

Please note: To ensure constant material properties the material should always be kept dry.
