Hi guy's, we run into asbestos once in a while, had a Zenith radio that the asbestos fell from the top of cabinet laying on top of the chassis. Found a replacement, I use a silicone baking sheet good up to 450 degrees. It sells in a roll easy to cut, but I found it very hard to glue so I just staple it in place. Find it in the cooking section at your favorite store.

I've been thinking of using Kapton. It comes in sheets or rolls of tape.
From an ebay auction:
"Polyimide is an advanced polymer originally developed for the aerospace industry. It has high temperature resistance over 300oC (572oF). At very high temperatures such as 350oC the film may become darker, buckle, but will not burn and will not melt on your work surface. "

Ceramic insulation is available in rolls, is inexpensive, and does the same jobs as the original, preventing heat damage or fire prevention.

+1 for Stephen's ceramic cloth recommendation.... Off eBay I got a sheet delivered for (I think) $9.

When I worked with it, they called it "ceramic mat."

You can buy those black cloth pads they use to protect surroundings when sweating pipes for plumbing work.

Yes, and they are carbon fiber.

Nomex used to be popular for hi-temp industrial insulation.

I think the EPA creates a lot of hipe on somethings and not enough on others. I was a plumbers helper before the service and when a heating system had to be replaced, someone had to remove all the old pipes and furnace. I was the one that removed all the old asbestos covering on all the pipes. The new pipes had to be covered and I think they were asbestos in the early 60's. You mixed up a batch of white stuff to cover all the joints and elbows. No gloves, just bare hands. Where's our plumber friend here? He might know. Anyway I was the helper for Tom Curley. I just hit 73 and Tom is 83. We're both still here with no health problems. Both EPA and California think everything is bad for you. The EPA really dragged their feet on a product from the 60's and 70's. We'll leave that one alone for now.

Even simpler just use aluminum foil. Yes I know its electrically conductive, but no one with any sense is going to use it under a chassis. Just make two or three layers and glue it or staple it to the underside of radio cabinet above the chassis. easy-peasy

I am an asbestos expert and owner of an environmental consulting company in it's 27th year. Some people who worked with asbestos for much less time died from it. The dangers are real and have been known for a century. Tobacco is a major factor, as exposure to both toxic substances greatly increases risk. We went from wild disregard of the risks to wild regulations and wild regulators, both silly extreme positions.

I get a little carried away sometimes and I agree with everything you said.
Very well put Stephen.

Some radio I restored in the past used the equivalent of aluminum foil glued to the board under the chassis. Yea, I think it is this Philco 84. Can see something like shiny foil sticking out under the rear edge. I guess if it is really well adhered to the surface it is not an issue.

somewhere in the shop I have about 10 little sheets of asbestos, must have come from one of the
repair shops I bought out. I have never needed one but would have no problem putting one in radio.
People think asbestos is toxic like radium or some such. Its only dangerous if you abrade it and INHALE it.
You have to make fine particles.
Not doing that.
