Delrin vs PTFE for poppet cupseal material
I bought a Delrin rod to make some new G6R poppet cupseals out of but I noticed that the material looks different than the stock cupseal material. I thought the stock material was Delrin but it seems like it could be PTFE.
Is there any real difference between the two when using them for face seals? I've looked up the material properties for both and it looks like Delrin is actually both stronger in tension and softer, so it seems like it be a better seal material, but I'm no material scientist.
