Asbestos fiber, a natural mineral fiber, was once popular worldwide for its excellent fire resistance, high-temperature endurance and insulation properties, and was hailed as a "miracle mineral".
The "hard core" nature of asbestos made it a "universal material" in the industrial and construction fields in the 20th century.
Due to its excellent properties, asbestos was once used in almost every aspect of our lives, and it was particularly common in buildings constructed before the 1980s.
