  • POM-CMaterial vergleichen

    POM-C is a highly crystalline thermoplastic. It is characterised by an extremely low water absorption, very high measuring stability and optimal processing properties (short-chipping). Because of the favourable properties – high hardness, stiffness and stability combined with good toughness and chemical resistance as well as favourable friction and wear behaviour – POM-C can be used in many cases instead of metallic materials.

    • Versatile high performance material
    • High stability and hardness
    • Very good cutting properties
    • Dimensional stability
    • Low water absorption
    • Very low creep properties
    • High chemical resistance
    • Good sliding properties
    • Physiologically harmless
  • 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 high mechanical hardness
    • High E-modulus
    • Excellent electrical properties
  • PEIMaterial vergleichen

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

    Most important properties

    • Temperature resistance (up to 200°C)
    • High stability and stiffness, even at higher temperatures
    • Very good electrical and thermal properties
    • High non-flammability
  • PE-HDMaterial vergleichen

    PE-HD is a partially crystalline thermoplastic, which is characterised by a high chemical resistance and good electrical insulating properties. It is widely used in the industry, because in almost every usual procedure it can be easily processed (very good cutting properties) and furthermore it is inexpensive.

    Most important properties

    • Very good cutting properties
    • Low density
    • Weldable
    • No water absorption
    • No moisture expansion
    • High stress cracking resistance
    • High chemical resistance
  • PVDFMaterial vergleichen

    PVDF combines good mechanical, thermal and electrical properties with an excellent chemical resistance. Because PVDF absorbs very little water, it is suitable for an unlimited use in liquids. The service temperature of –40 to +150°C offers a wide application area for this high temperature material.

    Most important properties

    • Temperature resistance (–40 to +150°C)
    • High stress cracking resistance
    • Very high chemical resistance
