The most common example of LBP wools are Alkaline Earth Silicate (AES) wools, which consist of amorphous fibers produced by melting a combination of CaO, MgO and SiO2.
Products made from LBP wools are generally used at application temperatures greater than 1100°F (600 °C) in industrial equipment, fire protection, automotive exhaust systems and domestic appliances. Their usage has grown significantly since their commercial production began in the early 1990s.
Products made from LBP wools are often used to provide high temperature insulation in industrial applications and fire protection.
