    Nylon and wear resistance - ptfe additives necessary?

    I would like to hold color to a fairly consistent benchmark, within a few shades of the oem at least. I'm not going after a scientific measure or expecting a miracle, but I would like it to be close. The color I'm matching is in the darker spectrum, not pastel at all, so it should prove a...

    Nylon and wear resistance - ptfe additives necessary?

    I'm working on a design for a motorcylce chain guide. This application won't see much loading, but it will experience friction and some heat from constant interaction with the chain. It's basically a plastic block through which the chain travels to keep it from slapping against the swingarm...
