How is it used?
Asbestos is a naturally occurring mineral and has been used for thousands of years, first used as far back as the stone age in cooking utensils. Its flexible and heat resistant properties made it a popular material for widespread usage in the construction and manufacturing industry.
A material most popular with manufacturers from 1900 to the 1970's. It was discovered that asbestos contained fire, heat, electrical and chemical resistant components, which made it a favoured insulation for steam engines, piping, boilers and car parts.
The building industry heavily used asbestos for cement since it provided good insulation and was generally lightweight. Most buildings built before the 1980's are thought to contain asbestos, and, if not disturbed, it can remain in the building structure without causing harm.Asbestos.com
