What is the affect of folding a PTFE Sheet repetitively? Would it cause the material to harden?

28 November 2017 1 1K Report

Multiple webpages (Including Wiki) state that FEP & PTFE do not withstand repetitive folding. Is the statement correct? and what would be the effect on the materials characteristics?

Peter Farrington

This paper has a very nice discussion of the mechanical properties of PTFE
