Friction Coefficient for Design Materials: PTFE, PP, PVDF, etc.

[jangolobow]

Hallo, does anybody knows where to get friction coefficients for different materials used in design (PTFE; PP; PVDF; PFA; TEFLON; VESPEL) or how to calculate them? Suppliers do not give a lot of data,..is there a theory behind to estimate friction coefficient? thanks in advance!

There is lots of theory but friction coefficients between two mating parts, since you are asking about static or kinematic friction, is determined by experiment.
