PTFE Laminates

Laminates are reinforced PTFE, consisting of a PTFE film or plate on the one hand and a substrate on the other. The 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.

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;
