Good Wear Material with Polycarbonate

[VELCROW]

Can anyone suggest a good material to wear against an injection molded unfilled polycarbonate part?

We have a polycarbonate "puck" which is a carrier for 6 test tubes. The puck is about 6” long, 1” wide, and 2” tall, and will ride on a conveyor. For part of the process, it will be driven by a belt on one side, and pushed against a wall on the other, so that we can move the puck at a more controlled speed than a simple conveyor. I am trying to determine the best material for a wall to minimize wear and friction. Ideally it should be readily available in sheet form.

Any suggestions for a good material? How would UHMWPE be? Any materials to avoid?

Thanks

Is the contact going to in the form of rolling or sliding contact?

A few more details like temperature, environment, etc. would be helpful.

UHMW polyethylene would be good place to start.

Sorry, sliding contact, only about 3 inches/sec, probably 10 to 20 lbs of force, which equates to 5 to 10 psi. But this is 8 hrs a day, every day.

Ambient temperature (70-80F), maybe dusty environment, no real chemical exposure except maybe a 10% bleach wipedown once a day.

Aside from the UHMWPE you might want to look at wear resistant Polycarbonate. Another one to evaluate is Rulon. The links I posred are not for the sheet form but both are readily available in sheet. Another one to check is the the Teflon Tapes. If they can be used it would cut down on the installed cost, the same with the Rulon Tape.
