Asbestos is a mineral that is found in natural settings such as caves and outdoor deposits. For many years it was used as an important ingredient in a large number of products, primarily for the construction industry, but it also had other applications. One such use was to create a strong fiber that could endure high temperatures and even survive fire. This made it more valuable than other materials that were used to created fiber, such as cotton or jute. Fiber that was made out of asbestos was built to last and to endure under most any circumstances.Application:
