Low Biopersistent Glass Wool (LBP)

  • Developed in the late 1980s
  • Commercially available since the early 1990s
  • Used in domestic appliances and industrial applications
  • Low biopersistence
  • Can be used up to 2300° F (1200 °C)
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.
