how much heat will bakelight take (I know spelled wrong)

I had a similar problem with my old Toyota fork truck. The battery had been moved near the exhaust pipe when it was converted to propane, so it used to boil the electrolyte. I used 16 gauge steel to build a shroud between the exhaust manifold and the battery, which appears to work beautifully. The battery runs quite cool now.

You might consider a simple metal deflector instead. Bakelite may, or may not, stand up to the abuse and heat.

It will take an unlimited amount of heat. You must mean temperature.

Continuous temperature for maximum resistance depends on the filler, from

300 (wood flour) to 375 (fiberglass) deg F. Loss of strength begins at 340 to 475 deg F likewise. (_Engineering Polymer Sourcebook_, R B Seymour.)

It will generally take just a bit less than you need and fall apart when you need it most.

Seriously though, I'm sure there is a web site out there somewhere that has data on this... Just don't know what it is yet!

This must be the one you're thinking of...

(Bakelite is a phenolic)

That's probably a bad application for bakelite, or any of the other similar materials like phenolic, or micarta.

I would use sheet metal instead, use two layers and sandwich some plain fiberglass insulation between them.

Bakelite was invented by Leo Bakeland in 1903, and was the *first* engineering polymer ever developed.

Use some foil "sandwich" material that is used on modern vehicles as heat sheilds. Usually under the car body where the exhaust comes close to the body or even the hood and fire wall. A client of mine makes this product. I would go to an auto junk yard and find a piece...would that work?

Hey Wayne,

How big a piece of material are you looking for. I've got some 1'4" thick "arc-shield" stuff from really large contactors that looks like really hard asbestos (no "loose fibres" that might do fine. It is NOT bendable.

Take care.
