PTFE Filled Plastic 4

[ShamrockPAPM]

I am looking to use a PTFE filled plastic in a gear application and I am trying to decide on what type of PTFE to use. What is the difference between a recycled PTFE and PTFE from Dupont?

PTFE is very expensive, so recycled is a good option. For some natural Dupont PTFE, I have seen it go for $5-7 / lb on the virign market, but under $.50 / lb for recycled pulverized. You will lose some M.W. property with recycled, but not enough that should cause a problem for gears in my opinion. Acetal, or POM is another good choice.
