Polysulfone (PSU) is a high-temperature aromatic sulfone polymer. PSU has excellent thermal and chemical resistance, making it well suited for demanding applications in automotive, aerospace, electronics, defense, food service, industrial, plumbing, medical, semi-con applications.
Attributes of Firewire® Polysulfone (PSU) include:
ThermaX™ PSU is an excellent alternative to ULTEM™ 9085:
Superior thermal properties (higher Tg and HDT) allow for higher strength and stiffness at elevated temperatures
Lower cost per kg and lower density (more filament per kg)
Recommended Print Conditions: (starting points)
PSU is sold by Solvay under the tradename Udel and by BASF under the tradename Ultrason S.
