  • PSUMaterial vergleichen

    Similar to PPSU and PEI, PSU belongs to the group of the amorphous high performance thermoplastics with very good mechanical, electrical and thermal properties for applications with higher service temperatures combined with mechanical stress.

    Most important properties

    • Temperature resistance (up to 180 °C)
    • Very good hydrolysis resistance
    • High chemical resistance
    • Good radiation resistance
  • PPSMaterial vergleichen

    PPS is an oxidation- and hydrolysis resistant plastic, which can be used for applications with a service temperature of up to 260°C. PPS has a low sliding friction coefficient and a high abrasion resistance. No water absorption, excellent dimensional stability as well as oil and fuel resistance are further properties. Because of the high hardness tight tolerances are possible.

    Most important properties

    • Temperature resistance (up to 260°C)
    • High stability, hardness and stiffness
    • High chemical resistance
    • Hydrolysis resistance (no water absorption)
    • Excellent dimensional stability
    • Oil and fuel resistance
  • PIMaterial vergleichen

    PI (Polyimide) is a crystalline plastic which is suitable for applications in the high and low temperature range.

    Most important properties

    • Temperature resistance (–200 to +300 °C)

    • Very good hydrolysis resistance
    • Good weldability
    • UV resistance
    • Very good flammability rating (V0)
  • PTFEMaterial vergleichen

    Polytetrafluoroethylene (PTFE) is a fully fluorinated polymer. Colloquially this plastic is often referred to as Teflon.

    Most important properties

    • Temperature resistance (–200 to 260°C)
    • Highly inert
    • High acid resistance
    • Low friction coefficient
    • Extremely low surface tension
    • Operation temperature up to 260°C; frost-resistant down to –200°C
  • PPSUMaterial vergleichen

    PPSU belongs to the group of the amorphous high performance thermoplastics with very good mechanical, electrical and thermal properties for applications with higher service temperatures combined with mechanical stress.

    Most important properties
