Polyphenylene sulphide (PPS)

Polyphenylene sulphide – it is engineering plastic retaining very good interbalanced mechanical, thermal, and chemical characteristics. Chemical name – PPS. It often replaces PEEK plastic in many areas, where good mechanical and chemical characteristics, stability of dimensions, economy, and relatively high temperature is required.

Polyphenylene sulphide – it may be produced with various additives like glass fibre or solid lubricant, as it provide this plastic with special characteristics. Plastic containing 40 % of glass fibre may be used within the interval till +230 oC. This type of plastic may replace lightweight metals.

PPS plastic is not warehoused, it is delivered only on special orders.


  • It features mechanical strength, rigidity, and hardness;
  • Stability of dimensions is ensured even under high temperatures (PPS with glass fibre);
  • Good anti-friction characteristics;
  • Non-flammable, self-extinguishing;
  • Easy mechanical workability;
  • Sufficiently good adhesive characteristics;
  • Resistant to hydrolysis;
  • Practically does not absorb water;
  • Chemically resistant to fuel, lubricants, fats, methanol, alkalis, water at +100 oC, to solvents, even at high temperature;
  • Features restricted chemical resistance to non-oxidising acids (depending on concentration);
  • Non-resistant to salt, nitrogen acids;
  • Colour: natural (brownish) and black.

Technical data:

  • Density: 1.35 g/cm3 (PPS);
  • Density: 1.65 g/cm(PPS with glass fibre);
  • Operating temperature: -20 oC - +220 oC;
  • Short-term operating temperature: +260 oC (PPS);
  • Operating temperature: 0 oC - +230 oC (PPS with glass fibre);
  • Reaction to fire class: V0 (UL 94).

*Sheets are produced only on special orders.

Scope of application:

PPS plastic is used, where it is required to ensure stability of dimensions, even at sufficiently high temperature: for production of diagnostic devices, liquid chromatographs, thermostats, and parts of test socket electronics.

Production of wheeled motor vehicles: for production of parts for engines, fuel injection systems, carburetters, and pumps.

Industry of electrics and electronics: for production of insulators, holders of carbon brushes, plug-in adapters, rosettes, housings of reels, and other parts.

Production of structural units: pumps, water gauges, valves, parts of valves, bolts, sealing elements.

Medicinal industry: for production of sterilisation apparatuses.
