Plastic wear 1

[cicciazzo]

Does anybody know if PA66 GF35 is compatible with PPA GF30 PTFE15 regarding wear?
Enviromental conditions are T= -30 to 130 Celsius degrees and a normal force of about 4 N.
I don't know the speed of contact point, but I presume it's quite high.
Sure not constant, parts are subjected to a on/off cycle.
Parts are 2.5 mm thick.

Follow the manufacturer's design handbook for acceptable PV factor.

One of the sources you could look at is LNP's

http://www.lnp.com

web site in the engineering graphical database (EGD) they have comparative tribological data. There used to be a lubricomp brochure with the kind of data you are after. Not sure if they still have it. Look at RF1007 against UFL4036. I think the 130°C is a bit high for the RF1007.
