Delrin is also very slippery. It works well as a bearing surface in
bushings and such.

Delrin is a tough plastic that is not brittle and subject to

cracking

like polycarbonate (Lexan) and it is somewhat sunlight (UV)

resistant.

It is also refered to by the name "Acetel".

It machines like brass except for drilled holes. With a twist

drill

the holes come out smaller than the drill bit so if hole size is
important then you have to ream them.

Great stuff for making prototypes or things that have to be an
electrical insulator. Works good at cold temperatures as well.
