POLYSULFIDES AND -SULFONES

Polysulfides and -sulfones

Polysulfides and polysulfones are high-performance plastics whose aromatic monomer units are connected to each other via sulfur bridges.

The amorphous polyarylsulfones include polysulfone (PSU), polyethersulfone (PES), and polyphenylene sulfone (PPSU).
Among the polyarylsulfides, only the generally semicrystalline polyphenylene sulfide (PPS) is of technical importance. All of these high-performance plastics exhibit a relatively high mechanical strength and a good temperature resistance, and are considered compatible with foodstuffs.

Main features

  • good mechanical strength
  • high dimensional stability
  • heat distortion temperature up to over 200°C

The amorphous polyarylsulfones (PSU, PES, PPSU) also show a relatively good transparency. These high-performance plastics are not completely transparent but slightly yellowish to reddish, but they still show a comparatively good light transmission of 75 to 85 %. Compared to other transparent plastics (PMMA or PC), however, they have a significantly higher temperature resistance.

We process the following polysulfides and polysulfones as standard:
