DOCASON PPSU MT
polyphenylene sulfone (PPSU), medical

Product features

DOCASON PPSU MT can be used for medical devices.

Black, Blue, Green

The use of PPSU is recommended when outstanding chemical resistance under mechanical stress is required. It can be used up to 190 degrees for short periods. It is highly resistant to hydrolysis, steam sterilizable, detergents and disinfectants. Impact resistance better than PEI and PSU materials. Widely used in the medical and food industries. Its medical grade (medical PPSU or PPSU MT) is available in several colours. Available in rod and sheet formats.

DOCASON PPSU MT

Some important features

  • High strength (yield strength 50-105 MPa, tensile strength, compressive strength)
  • High toughness - does not break
  • High hardness (Rockwell: M 75 - M 114)
  • Wide application temperature range: -50°C to +190°C
  • Very good chemical resistance
  • Physiologically neutral, may come into contact with food and medicines
  • Dimensional stability, good damping capacity
  • Favourable creep resistance (10-30 MPa for 1% tension at 1000 h at 23°C)
  • Good electrical insulating and dielectric properties
  • Good resistance to high-energy radiation

Main areas of application

Machine components and sub-assemblies, mainly in the food industry, medicine, which have to be cleaned and sterilised frequently (e.g. milking machines, heat exchangers, filters, pumps, etc.).

Machining technology

Chipping (turning, milling, drilling, sawing): conventional tools can be used, but only with a sharp finish. Cooling is recommended, with cutting speeds of v = 200-400 m/min for turning and milling, v = 50-100 m/min for drilling.

Gluing: is feasible (but more difficult than PVDF with similar properties).

Available formats

  • PPSU plate
  • PPSU rod
