Why did we use so much Asbestos: Asbestos is a great material for the manufacturing and construction industry. It does not burn and transmits heat very poorly, making it a great insulator against heat. It is a poor conductor of electricity and is also used as an insulator against electricity. It resists rust and can be used in exterior applications. Asbestos is a strong material and yet flexible. It has the soft and pliable qualities of cloth making it useful in protective clothing. Asbestos can be applied to a product by spraying painting it on or it can be added to a product such as concrete.
