Ultrafuse® PPSU

Welcome to the World of High Temperature Stable Applications!

Ultrafuse® PPSU was specially developed for FFF printing based on BASF ́s advanced Ultrason® materials. The Ultrason® resins are amorphous thermoplastics derived from polyethersulfone (PESU), polysulfone (PSU) and poly- phenylsulfone (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.
