Information Booster: Mineral fibers are highly durable and resistant to heat and chemical attacks. Asbestos is widely used for fireproofing and insulation, while glass fibers are used in composite materials like fiberglass.
Additional Knowledge:
· Regenerate fibers: Made by chemically treating natural materials (e.g., rayon).
· Artificial fibers: Synthetic fibers like nylon and polyester.
· Metal fibers: Derived from metals like aluminum or steel, used in specialized applications.
