They can be. Typically, they are made from HDPE -- high-density
polyethylene.
A very expensive material for that application.
Probably not FDA approved.
Cutting boards usually made from polyproplene or maybe HDPE (High density
polyethylene).

Here is some 3/4" thick stuff for $4 a square foot.
That would make a lot of jigs...

I get 100 bf of the stuff, or $4/bf. That's cheaper than a lot of
wood people make cutting boards out of.
Actually
600' x 2" = 100 sf
100sf x 3/4" = 75 bf.
$5.33 / bf + shipping
I think that hdpe which is softer makes a better cutting board. They also
texture it so that the food doesn't slide off!

Nor are our air, water, or most foods any more. Sigh...

FWIW, Lew, UMHW -is- HDPE, just a denser form.

And considerably more expensive.
I made my rudder post bearings from it.
Got a block about 12"x12"x6" that was in the remnant pile at my plastics
source, and even that was expensive.
Also, as with many plastics, tricky to machine since it has a relatively
high thermal coefficient of expansion.

I figured 3/4" finished counted as 1" rough for the bf calculation, just
like it would for hardwood :-)

Are you using this in salt water? If so, how has it held up?
I'm considering getting a couple of pieces of UHMW polyethylene to
machine outhaul line guides for my for my kayaks and dinghy's. The
surface of bronze and stainless steel guides gets too rough after a
couple of years.

Back when I was selling UHMW we put a couple of pieces in salt water
to see if barnacles would adhere (they didn't) and there was no ill
effect - actually there is hardly any chemical that will affect it. If
exposed to sunlight be sure to get black repro or UV stabilized if you
want white.

You might be better with HDPE. HDPE isn't just low-weight UHMW, it's
also processed differently (I don't know the details) to give better
mechanical properties. UHMW is a bit soft, and repeated use of a line
across the same spot will cause wear grooves pretty rapidly.

Chicken deboner cones?

Are you questioning what they are?? In a kill plant one process uses a
conveyor with plastic cones mounted on stainless threaded rods. They
stick the chicken on the cones (kinda like "beer butt chicken" on the
grill) and workers cut off the various parts of the chicken as it
moves down the line. As the cones become nicked from the knives they
must be replaced. HDPE works well but is being replaced by other
harder materials.
