This may be a simple question, but it PTFE incompressible? I have a graphite filled teflon material used for a lip seal and want to do some preliminary analysis. I need to know the poisson's ratio of the material. I have some experience dealing with elastomers but little experience with PTFE and other polymers that may be used for seals/bearings like Torlon, PEEK, etc. Some good introductory book recommendations on polymers would also be helpful. I am a mechanical engineer that knows metals but feel a little intimidated by polymers and I'd like to educate myself.
Thank You
