After mining or quarrying, the asbestos fibre is freed by crushing the rock and is then separated from the surrounding material, usually by a blowing process. Only the longest of the fibres, at least 1 cm (0.4 inch), are suitable for spinning into yarn.

Asbestos is a generic name given to six fibrous minerals that have been used in commercial products. The six types of asbestos are chrysotile, crocidolite, amosite, anthophyllite asbestos, tremolite asbestos, and actinolite asbestos. Several properties that make asbestos so versatile and cost effective are high tensile strength, chemical and thermal stability, high

there were some mineral wool products that deliberately combined asbestos, such as layers of asbestos paper, with mineral wool, and other inventors experimented with combining other fibers such as flax with mineral wool to reduce its tendency to settle in vertical installations such as wall cavities.

Oct 01, 2020 Asbestos is an effective insulator, and it can be used in cloth, paper, cement, plastic and other materials to make them stronger. But when asbestos dust is inhaled or ingested, mineral fibers can become permanently trapped in the body. Over decades, trapped asbestos fibers can cause inflammation, scarring and eventually genetic damage.
