Laminates and Foils based on PTFE and modified PTFE for Container Linings

  • Outstanding resistance to a wide range of chemicals
  • Very broad functional temperature range, only limited at the upper end by resistance of the adhesive used
  • Very good antiadhesive properties for container linings and pipe linings
  • Dimensional stability and resistance to stress cracking
  • No embrittlement, no ageing

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
