Help with plastic selection
(OP)
I apologize if this isnt the correct plastic forum, but it was the closet I could find...
I'm in need of a plastic recommendation for a design. For all intents and purposes it can be thought of as a wiper for a wire rope. I need:
-High wear/abrasion resistence
-Some degree of natural lubrication
-Good elasticity properities (flexible)
-Impervious to most factory environment chemicals
-Injection moldable
I have no plastics experience, but my initial thoughts were low density PE, TPRs, or polyurethane. Can anyone give me a better recommendation, something more specific or point me in the right direction? Any info is appreciated.

Nylon will be best if high speed or high pressure generates a lot of heat.
Polyethylene will be cheap and has a greasy surface, but has a very low softening temperature.
Polyurethane has good flexibility and abrasion resistance, but the temperature resistance is not as good as nylon and the lubricity is not as good as PE
