Ultrafuse® PPSU was specially developed for FFF printing based on Forward AM´s advanced Ultrason® materials. The Ultrason® resins are amorphous thermoplastics derived from polyethersulfone (PESU), polysulfone (PSU) and polyphenylsulfone (PPSU) and ensure very high thermal resistance.

With its wide spectrum of material performance advantages, Ultrafuse® PPSU can be successfully used in applications where other plastics, e.g. polyamide, polycarbonate, polyoxymethylene and polyalkylene terephthalates, fail to meet the performance specifications.

With its inherent flame retardant properties, it is an especially suitable material for the aerospace industry.
