Polyether sulfone (PES)

Polyether sulfone (PES) together with PSU and PEI forms a group of amorphous aromatic high temperature plastics. PES is characterized by very good creep properties, excellent chemical resistance and is flame retardant without any additives.

PES Properties

  • Amorphous structure with glass transition temperature of 220 C
  • Transparent
  • Excellent hydrolysis resistance
  • Good chemical resistance
  • Good temperature resistance
  • Low uptake of microwaves

PES can be used in many places, like high-performance industrial applications, in automotive and electronic components. PES is also well suited for medical parts because the material can be repeatedly sterilized in superheated steam. After more than 100 sterlization cycle, it remains transparent and largely retain its high level of mechanical properties.
