Temperature Range, Impact Resistance

PPSU for CNC Machining

PPSU is a thermoplastic material that can endure high temperatures and offers exceptional impact resistance. It is resistant to hot water and steam, and it can endure multiple cycles in a steam autoclave.

Please note

The information contained herein are typical values intended for reference and comparison purposes only. They should NOT be used as a basis for design specifications or quality control.

Design Tip

To minimize costs, reduce the number of part setups, inspection dimensions, or strict tolerances, and avoid deep pockets with small radii.

Hardness

Material hardness is based on the Rockwell Hardness Scale.

High temperature thermoplastic with excellent impact resistance

PPSU

PPSU (polyphenylsulfone) is a high temperature thermoplastic material with outstanding impact resistance. It's resistant to hot water and steam and can withstand repeated cycles in a steam autoclave.

A general purpose extrusion grade of PPSU offers exceptional hydrolytic stability and better toughness than most commercially available high-temperature polymers. 

Performance Characteristics

  • High heat deflection temperature
  • Excellent thermal stability and impact resistant
  • Good chemical and environmental stress cracking resistance
  • Steam and radiation resistant
