Asbestos fibres are modified natural fibres. Long regarded as a wonder material for its excellent thermal isolation and electrical insulation abilities. Recognised as a dangerous substance because of its tendency to cause lung cancer. It differs from other inorganic materials in the same category as glass fibre, carbon fibre, basalt fibre and ceramic fibres. It does not need any heat or chemical reactions to produce it. At first sight, it would appear to be a popular product.
Nevertheless, the equipment needed for these purposes is heavy and can be dangerous; only a few eras considered to be suitable material unless other options, as in firefighters’ uniforms, foundry clothing and similar protective garments. See also inorganic fibres.
