PBI

PBI fibers are an excellent choice for very demanding applications. They are often used for safety and heat resistant garments like safety gloves, and firefighter uniforms. PBI is also used as a plastic reinforcements, for heat and chemical resistant filters, and for various other civil engineering applications. The fiber is often blended with other high performance fibers like Kevlar.

PBI fibers are suitable for a wide range of high temperature applications. The fiber is flexible, has low tenacity, low moisture regain, does not burn or melt, and has an outstanding strength-to-weight ratio. Typical application for PBI yarn and fibers include:

• needlefelt
  thermal insulation, safety and protective clothing, fire blocking
   
• weaving
