Asbestos is a mineral fiber composed of chain silicates, including minerals, amosite, crocidolite, chrysotile, fibrous actinite, fibrous anthophyllite and fibrous tremolite. Asbestos is used in hundreds of consumer products. As long as it occupies less than 1% of the product, it is allowed to be used. Asbestos can split into very fine fibres which can remain airborne for long periods of time after release. Asbestos Test Kit https://www.cd-testkit.com/asbestos-test-kits.html
