Why is it so costly? Is there a cheap hook up for it? Is there another product that will mimic the performance with less cost? General use, making spring guides and other airgun parts?

Let's talk Delrin.
- Thread starter Hw9720
- Start date
i guess it depends what kind of production you need .. i can get a couple of foot long 1" rods on amazon for about 12 bucks acetal/copolymer/delrin .. pretty sure its all about the same thing .. brass now, youre getting pricey lol ..

It has been a few years but I used to get it for a pretty good price at McMaster Carr in Cleveland.

"Sur-Seal PTFE-0.50x12-RD PTFE Teflon Rod, 1/2" Diameter x 12" 12.18 than add shipping and tax and that's more than a dollar an inch.
It looks like prices run on Delrin .50 cents to a dollar a INCH
That still seems high to me.

Closer to 40 cents/inch. Think about it this way though, it costs $3 to make a guide and 40 cents to make a top hat

Delrin is just a trade name or name brand if you prefer. Actual is the base material. If you look for that you'll probably save some money. The company I work for use to sell it. Most of the time you can get it in black or white. In rod we stocked it from .250 diameter up to 3" diameter. Check with Laird plastics they will probably still have it. Hope this helps.

PET-P is a good alternative. to Delrin / acetal. Low cost and similar properties.
PTFE has great self-lubricity but is quite soft in comparison.
Here's a table of common plastics I compiled a while back...

Sorry, my OCD is kicking in...
NOT Delran, its Delrin, Polyoxymethylene (POM), acetal resin.
It's not expensive and it's not as good as PEEK and that's pricey!
