What is PSU?

Polysulfone (PSU) is a family of transparent thermoplastics known for their toughness and stability at high temperatures. A semi-crystalline polymer, PSU is rigid and highly resistant to mineral acids, alkalis and electrolytes.

Main Attributes of PSU:

  • Good chemical resistance (mineral acids, alkali, salt solutions)
  • Flame retardant
  • High strength & stiffness
  • Excellent dimensional stability
  • Lubricated
  • High heat resistance
  • Broad temperature range capability
  • Good creep strength
  • Good resistance to hydrolysis and steam
  • High mechanical strength
  • Good insulating and dielectric properties
  • Semi-transparent
  • Typically has an amber tint
  • Food grade variations available
  • Not UV resistant and poor weatherability  – unsuitable for outdoor applications
  • Not suitable for esters, chlorine and aromatic hydrocarbons
