Need something between two electrical conducting surfaces but it must also be fireproof. No thicker than cardboard, and about 1/2" wide x 4" long.
Any suggestions?
Do a search for: braided wire ground strip
Suspect you can find shorter and narrower ones, but this style will work: AC/DC WIRE AND SUPPLY Bare Copper Flat Braid Ground Strap Grounding 1" Width... (http://www.amazon.com/AC-DC-WIRE-SUPPLY-Grounding/dp/B07S9GZRN9)
BRIGHT COPPER GROUND FLAT BRAID 1"
MADE IN U.S.A
.045" THICKNESS
CAN BE USED FOR GROUNDING - GROUND STRAPS - WIRE SLEEVE/PROTECTION - ET
I like to think that I am not the average idiot, but a slightly above average idiot, but...doesn't copper conduct electricity? Isn't that what most wiring is made of (or Aluminum)?
To insulate between conducting surfaces this might work:
CeraTex 3170 Ceramic Fiber Paper, Size 11" x 12" 3 Sheets, 1/8" Thick(or Select 1/4", 1/16", 1/32") High Temperature Insulation Gasket or Liner for Kiln Stove Furnace Glass Fusing

Norm,
Sorry, was not clear you wanted a NON-conductive product.
It sounds like you want a piece of FR4 material. Here is a supplier. There are also vendors on Amazon.
Huge Selection of G10 FR4 Epoxy Fiberglass Sheets Available at ePlastics (http://www.eplastics.com/fiberglass/sheets/g10-fr4-epoxy)
Per their website:
G10 and FR4 glass cloth reinforced epoxy natural is typically a yellowish to light green color. The most versatile all-around laminate grades are continuous glass woven fabric impregnated with an epoxy resin binder. Epoxy resins are among the most versatile and widely used plastics in the electronics field, primarily because water absorption is virtually nil, rendering it an outstanding insulator.
Beyond its electrical insulating properties, epoxy resins exhibit great dimensional stability (shrinkage is usually less than 1 percent) and superior adhesive properties. G10/FR4 has extremely high mechanical strength, good dielectric loss properties, and good electric strength properties, both wet and dry.
The main difference between NEMA Grades G10 and FR4 is that FR4 is a fire retardant grade of G10. Therefore, FR4 can be safely substituted where G10 is called for, while G10 can never be substituted where FR4 is called for. G10 meets MIL-I-24768/2 GEE and FR4 meets MIL-I-24768/27 GEE-F.
I use scrap Filon for projects like that.
Use a box cutter knife and cut a piece of Hardie Backerboard to fit. Seal it with water based primer/paint.
