* water filters
* hair dryers
* space heaters
* anti-scorch pads (stoves and bunsen burners)
* HVAC duct sealing
* boiler, pipe, and duct insulation (buildings, machinery, vehicles)
* brakes

Just get a big tub of loose asbestos fibre and use a blower to fill the roof space. What could go wrong?

There were times when you could have been surrounded by the stuff in your own home.
It was also boxed up in pure form and sold as artificial snow.
It was really in many places due to its great thermal properties. But plastic permeated everything these days, thats on another few orders of magnitudes higher level.
