Our materials

  • Laminates are reinforced PTFE, consisting of a PTFE film or plate on the one hand and a substrate on the other. PTFE foils are available in a wide range of thicknesses and widths.
  • The laminate layers of material are firmly bonded to each other. Possible substrates include fabrics, fibers, or knitted fabrics as well as films.
  • They consist, for example, of glass, metal, ceramics, elastomers, or high-performance polymers. The structure may comprise two or more layers, and constructions with up to 7 layers are not uncommon.

When modified PTFE is used as a film material, these properties are enhanced further by:

  • Polymer structure with higher density and fewer pores
  • Lower permeability
  • Better weldability
