Polyphenylenesulfide (PPS) is an aromatic, semi-crystalline high temperature thermoplastic with a glass transition temperature of 85 – 90 C and a crystalline melting point of 280 – 290 C. Its main features are excellent creep resistance, outstanding chemical resistance to a broad range of organic and inorganic reagents up to elevated temperatures, and inherent flame retardancy.
The use of PPS in its natural form is restricted by the modest mechanical properties. Adding fibrous reinforcedments enhances the mechanical performance dramatically. As a result, the bulk of the applications are in reinforced PPS.
- Excellent creep properties
- Phenomenal chemical resistance against almost any solvent
- Exceptionally high stiffness and hardness up to 80 C
- Inherent flame retardancy
- Superior flow properties compared to all other high temperature polymers
- Brownish base colour which limits colourability
- Modest impact strength
