BASF Ultrafuse PPSU
Welcome to the World of High Temperature Stable Applications!
Ultrafuse PPSU has been specially developed for FFF printing, based on BASF’s advanced Ultrason materials. Ultrason resins, amorphous thermoplastics derived from polyethersulfone (PESU), polysulfone (PSU) and polyphenylsulfone (PPSU), guarantee very high thermal resistance.
With its broad spectrum of performance benefits, Ultrafuse PPSU can be successfully used in applications where other plastics, such as polyamide, polycarbonate, polyoxymethylene, and polyalkylene terephthalates, fail to meet performance specifications. Due to its inherent flame-retardant properties, it is particularly suitable for the aerospace industry.
Available in natural amber color, 750 grams, diameter 1.75 mm.
