Uneven wear of plastics rotating plates
Uneven wear of plastics rotating plates
(OP)
I have two plastic round plates (disks)in contact. One is rotating against the other one. (A type of brake application). The wear of the thickness of the plates is uneven. A cross section would show a wavy pattern from the inside radius to the outside radius. Any idea what could cause this? thanks.

Nylon 4.6 (Stanyl by DSM) is an interesting material if you are looking for excellent PV.
You might not see it listed outside DSM's data as it is a relativly new polymer.
It is very highly crystalline, and as such is not all that mould temperature sensitive (re crystalisation) as it reaches it's maximum crystalinity almost instantly.
It has good physicals up to it's melting point of about 300 deg C. A major application because of this is Automotive Timeing Chain Tensioners and Guides, where it typically tests at over 3 times the life of MoS2 filled nylon 6.6, and up to 10 times in one case
