PPSU - Formfutura

FormFutura PPSU (Polyphenylsulfone) is an amorphous ultra-performance 3D printing filament based on sulfone polymer from Solvay. PPSU has a glass transition temperature of 220°C and 3D printed parts with PPSU filament can operate in temperatures up to 180°C. This makes PPSU extremely suitable for automotive applications around the engine and cylinder block as PPSU is resistant against most common automotive fluids. PPSU filament is also perfect for 3D printing medical applications as 3D printed parts with PPSU filament are qualified for unlimited steam sterilization through among others EtO gas, radiation, steam autoclaving, plasma, dry heat and cold sterilization. FormFutura PPSU meets the ISO10993 standards for medical applications.
PPSU offers a better impact resistance and chemical resistance compared to PEI and is inherently flame retardant to UL 94 V-0 standards with low smoke evolution and low smoke toxicity.
