  • TFE & Compounds

    TFE – Quite an Extraordinary Material

    The semi-crystalline TFE (tetrafluoroethylene) is synthesized from the monomer TFE by polymerisation. The bond between carbon and fluorine is one of the strongest and most stable bonds in organic chemistry.

    TFE is very well known under the name Teflon® (DuPont) and Hostaflon® (Dyneon).
    Physical and Chemical Properties of Unfilled TFE

    TFE combines the most outstanding properties in one polymer, such as

    • a broad thermal range from -260 °C to +280 °C (for short times)
    • an almost universal chemical resistance
    • it is photostable
    • weather-resistant
    • resistant to overheated steam
    • it has optimal gliding properties
    • and it is non-stick and not flammable

    TFE and TFE compounds are reliable sealing materials with long livecycles and excellent chemical resitance.

    To achieve the optimal functionality and system stability users must define the best combination of seal design, TFE compound and surface finished. Rely on our experts to help you find this combination.

    Filled TFE Compounds

    Adding fillers to TFE can

    • extend the useful life of the TFE component
    • change the wear and tear on the surface opposite the seal
    • increase the resistance to plastic flow or deformation under stress
    • significantly increase the heat conductivity
    • decrease the thermal expansion and
    • change the electric properties of TFE
  • PEEK

    PEEK - Polyetheretherketone

    PEEK is a high strength thermoplastic material with very good chemical resistance.

    This polymer maintains its excellent properties up to a temperature of 300°C
    PEEK is for example used for guide rings and ballvalve seats, which must perform
    to the highest standards.

    PEEK is very well suited for applications at subzero temperatures down to -100°C.

    PEEK has excellent chemical resistance

    • radiation (nuclear energy)
    • mineral oil-based lubricants
    • petrol
    • hydrocarbons
    • weak mineral acids and inorganic acids
    • alkaline solutions
    • acetone
    • alcohols
    • hot water, steam

    The low specific weight of PEEK keeps the weight of PEEK components down.
    The heat expansion ensures a small clearance

    PEEK can replace metal because it combines great stability with an enormous weight advantage.

  • Composites - Fibre Composites

    Composite materials - fibre-reinforced composites

    The unique properties of composite materials are used in applications with the highest safety, reliability and cost effectiveness requirements. In addition to the benefits they offer with regard to service life and operating costs (life cycle costs), composite materials also have the advantage of being lightweight!

    Key advantages of the parts with high performance characteristics:

    • Low thermal expansion
    • Low inertia
    • Low weight
    • Universal chemical resistance
    • High corrosion resistance
    • Hot water and steam resistance
    • Antimagnetic
    • Permeable to X-rays
    • High bending strength and stiffness
    • High torsional strength
    • Outstanding wear properties

    These materials are based on carbon fibre materials bonded with PEEK.

  • Elastomere

    Elastomers

    The Material for Top of the Line Seals and O-Rings

    Areas of application in which the operating temperature, operating pressure, compatibility of chemicals and the installation situation are particularly important.

    We offer elastomers with individual and outstanding properties.
