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.

Material Details

Description

Due to its wide range of material performance advantages, Ultrafuse® PPSU can be successfully utilized in applications where other plastics, such as polyamide, polycarbonate, polyoxymethylene, and polyalkylene terephthalates, fail to meet performance specifications. Its inherent flame-retardant properties make it particularly suitable for use in the aerospace and railway industries.
