XYMON, an All-New Type of Fluoropolymer Compound

Xymon – ElringKlinger’s new composite material based on fluoroplastics – is far superior to conventional PTFE compounds in terms of its mechanical values, with no sacrifice made to its outstanding chemical properties.

Properties

  • Virtually universal chemical resistance
  • Extremely high tensile strength
  • High pressure resistance
  • Superior cold flow resistance
  • High abrasion resistance

Application examples

  • Valve seals
  • Valve seats
  • Valve flap for gas compressors
  • Plates for wafer-carriers
  • High-tensile cover sheets for pumps
  • Pump vanes
  • Spacer in pipe bundles for heat exchanger

Synthesis
Xymon is a fluoropolymer compound reinforced by long carbon fibers (C-fibers) with an anisotropic property profile. It is manufactured as a plate, disc or ring. The main orientation of the long carbon fibers is in the xy-plane:

All fibers are evenly dispersed in the xy-plane.

Compared to unfilled PTFE or typical compounds with carbon or glass fiber fillers, there is an immense gain in properties, measured parallel to the fiber orientation:

Physical Data

  • Elasticity modulus: 5000 MPa (parallel to fiber)
  • Tensile strength: 45 MPa

Standard Dimension

  • Thickness 4, 5, 6, 10 mm special dimension 1-30 mm
  • Width: up to 750 mm
  • Length: up to 1250 mm

    Chemical Resistance
    The very good resistance of the C-fibers and the fact that they are tightly enclosed by the fluoropolymer give Xymon its unique resistance which closely approaches that of pure PTFE. The material may be used, for example, in hydrofluoric acid, hydrochloric acid, phosphoric acid, mineral oils, tetrahydrofuran and many other media.
