Can asbestos melt?
Asbestos can melt, if it gets hot enough.
Asbestos was a useful ingredient in making fireproofing because it is a mineral that will not burn and requires very high temperatures before it will melt. Unfortunately, exposure to airborne asbestos, if it lasts long enough, can result in serious diseases such as asbestosis, lung cancer, and mesothelioma. As a result, asbestos is no longer permitted to be used in fire proofing in most countries.
Most synthetic fabrics made of plastic such as polyester will melt when heated enough as in a microwave. Natural plant/animal fiber fabrics such as wool, cotton, linen will not melt but will burn at high temperatures. Mineral fabrics such as asbestos will neither burn or melt unless exposed to extremely high temperatures.
What is the hard black stuff on old floors that has to be chipped off and adhesive remover will not melt or penetrate?
Is the asbestos that we used in the late 60's to make modeling clay for children the same asbestos that is now banned?
The difference between corrugated asbestos roofing and flat asbestos cement sheet is the form in which it was cast and, perhaps, the thickness of the finished product. Asbestos was merely an additive to cement. Both products are basically cement with a fiber strengthener that happens to be asbestos.
