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.

Properties
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;
Dimensional stability and resistance to stress cracking;
No embrittlement, no ageing;

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;
Application:Linings in plant engineering;Components for electrical and electronic applications;Diaphragms in pump or sensor construction;Optically transparent compounds for textile construction;
