Great. Thanks John. The silicone is particularly intriguing.

You might try looking at some ferrite polymer material sheet stock, though most mfrs are only interested in surface finish resistivity of the treated material.
They are not designed for use as strictly resistive materials, so who knows what they would do over a range of temperature or pressure.
Where defined, published resistivity shows a range between 500 and 21 ohm-meter, below 10KHz.

Not flexible; brittle. Also not usually available in sheets.

Please read the frigging spec sheets, on the links provided, before commenting.
Polymer materials are available in sheets, rolls, or injection molding pellets.
The problem with filled polymers is dimensional instability - hence their use in pressure and humidity sensors and a restricted environmental range - and problems using them as a heaters. When deposited in thin fims on mechanically rigid formers, they have more common applications.
The usual method of producing conductive/resistive polymer is to carbon fill, but just try to locate a vendor of sheet stock with resistivity lower than the typical ESD dissipative ranges......
