Asbestos is a silicate mineral rock and is used in building materials and has fire resistance property. Asbestos can resist high temperature, many chemicals and wear. It is also a poor conductor, therefore it insulates well against electricity and heat. You can find asbestos materials in walls, ceiling, roof and pipe covering.
