How about Plexiglass?  I've been using the stuff for many years as end insulators for my dipoles.  I buy a sheet and have the hardware store cut it up in pieces for me.  I have enough insulators to last me a lifetime.  It's very strong material and can handle weather very well.

1/4 or 3/8 PEX tubing...probably has no UV protective additives.

FWIW --

I used some white 1/2" PVC pipe for standoffs on my boat.  They were in tropical sun for a few years.  No degradation at all.

PVC pipe is cheap, and easy to cut into short pieces.  Suggestion:

. . . A slot in each end of each piece holds the wire. 
. . . A black plastic wire tie, inside the pipe, holds the wires in place.

The black plastic ties last for years in the sun (longer than white ties), but not forever.  Wrap the ends of the PVC in black electrical tape to keep the sun out, to increase their life.

I used .5" polycarbonate tubes from tap plastics.  I cut a bunch of them to the same length, drilled a hole through about .5" from each end, pulled the wires through the hole and used a hot glue gun to set them.  Polycarbonate is UV resistant and has a very high melting point so the hot glue gun doesn't faze it.
