Chain guide - What type of plastic?
I'm refurbing my 2004 chain guide, the side cheeks are 3mm thick plastic.
Can any plastic experts suggest the best type of plastic to use? Obviously needs to be oil resistant and tough but not brittle. Would teflon/PTFE be suitable? Thanks, Dave. Last edited by Davehuge; 09-06-2018 at 11:41 AM.

For anyone that's interested...
I've just spoken to a plastics supplier and explained what I wanted to use the plastic for. He said PTFE has a very low coefficient of friction but would be too soft, it wouldn't last long. He has recommended Nylon, it's cheaper too!  Just ordered a small 3mm thick sheet for 3 euros. Last edited by Davehuge; 09-06-2018 at 11:26 AM.

Thanks! I will need to do this in the near future on my 2000 EC.

Just to save any confusion...I'm refurbing the old style of 'swinging' chain guide...

Been many years but have used Celcon in the past for a lot of automated machine parts. I think it is a variation of Delrin. It was more dimensionally stable so it machined better than nylon or Delrin. Nylon is definitely low cost.
