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.
