Polyphenylene sulfide (PPS) is a thermoplastic material with outstanding chemical resistance – even at application temperatures up to +20 °C. Due to its flame resistance, good mechanical properties, low creep tendency, and high resistance to weathering and radiation, PPS occupies an important position among high‑performance plastics. PPS GF 40 significantly increases the tensile strength of the material through the addition of 40% glass fibers.
In practice, PPS is used for technical plastic components almost exclusively in reinforced form. In this state, it becomes a very rigid high‑performance polymer with numerous properties in the top performance range, such as:
- high strength, even at elevated temperatures
- high dimensional stability
- high temperature resistance
- good electrical properties
- excellent chemical resistance
- low interfacial diffusion
- flame retardancy
- however, it tends to exhibit brittle fracture behavior
