I think that a company called Stone Industries made the CMR and MPC tubes. An interesting thread on the subject can be found here: http://www.rocketryforum.com/showth...like-body-tubes .

I did a search and this came up: fishpaper An insulating paper, often fiber- or oilcloth-like, used in the construction of transformers and coils. [Historical Note: Alvin G. Sydor writes: "In 1729 Stephen Gray made the discovery of the conducting and non-conducting power of different substances. Gray found that by using woven silk served as an excellent insulator. Some years later it was found that the paper industry could provide what was equivalent to woven silk. Later it was discovered that if the paper was saturated with fish oil its ability as an insulator was much improved particularly when used in harsh environments and high voltages."

Yes. If you remember taking apart electrical things as a kid, many times a flat square of the material was wedged in or screwed down between components. I don't see it used much that way these days. It usually varies in color from a medium grey to almost black, with green hues and blue hues. I've even seen some that had a rusty red color, but I 'm not sure if it is considered fish paper. I doubt today's fish paper uses fish oil, but it might. Seems like epoxy resins would be the way to go and would explain it's strength/stiffness.

Thanks to Chris, we now know that model rockets (most if not all of whose parts are biodegradable, sunlight-degradable, or 'oxidation-degradable,' especially those having balsa or hardwood nose cones and balsa--or fiber--fins) have even *more* sourced-directly-from-nature materials than we had previously known. I would never have guessed that the "Stone-ized" stage coupler paper is called fishpaper because it contains actual fish oil (but it does make perfect sense from an electrical properties perspective, as oil--not fish oil--is also used in large transformers). I wouldn't be surprised if some small, low-powered transformers (and perhaps even paper condensers [capacitors]) use fishpaper as an insulating material, and: The "loopstick" antenna coils (ferrite rods inside paper sleeves, with the coils wound around the sleeves) that are utilized in radios might use fishpaper sleeves. Plus, for winding "air core"--having no ferrite rod--antenna coils (these larger coils are often used in crystal radios, antique and old-style AM and Short Wave radios, ham radio transmitters and receivers, wave traps, and ATUs [antenna tuning units]), fishpaper stage couplers would make excellent coil forms to wind the wire (usually enameled wire ["magnet wire"]) around, and they are probably cheaper than bakelite plastic and phenolic-impregnated paper coil forms.
