Delrin is a name brand of Celcon, FYI. Like Kleenex is to a tissue

That’s not quite right. Delrin and Celcon are both name brands of POM Plastic, but they’re a bit different.
To quote this guy who actually corrected me a bit ago when I said they were exactly the same,

@daniel0731ex

They are practically the same, but not exactly. Delrin is homopolymer while Celcon is copolymerized for easier injection molding. The reason for this is due to the dramatic shrinkage that homopolymer POM undergoes during injection molding. The copolymer version still shrinks like heck, though, just a bit more managable.

You said homopolymer goes through dramatic shrinkage…hehehe I’m so immature
