Heat Tolerance

[creativewriting]

I am curious if anyone knows of a plastic or plastic like rod that can withstand baking at 350F for a few minutes. In the past I was using aluminum and brass, but wanted to see if any of the other pen turning materials (i.e. ebonite, PR, etc.) might be able to withstand a quick trip in the oven. I was on McMaster Carr and a few other sites, but I am not familar enough with the materials to know what might stand up to threading and taping.

Why?

I am a polymer clay person. The clay needs to cure in an oven at 350F. 10 minutes per quarter inch thickness. I would like to turn some forms that are not metal that are then wrapped with polymer and cured.

something like UHMW or Delrin may work for you. They have a very high density and are less susceptible to heat damage. May want to try a small piece by itself to make sure first and be careful of potential fumes.

also PEEK http://www.usplastic.com/catalog/item.aspx?itemid=23829&catid=618 but it ain't cheap.

Damn...you are right about the cost. I might have to stick with aluminum and brass for now.

UHMW PE will not withstand 350, but I have used polymer clay to fill carved sections in PR as well as wood many times very successfully. Alumilite should work also and very easy to test.

Corian !!!!! It withstands temperatures of 366 degrees and is easy to turn as plastic.

also PEEK Ketron® PEEK 1000 | U.S. Plastic Corp. but it ain't cheap.

$4.59 for 1/4" x 1' rod ain't too bad....
