Strength After Thermal Exposure

PBI fiber, chemically known as polybenzimidazole, is a fiber that goes into many blends for a variety of inherently FR fabrics. PBI fiber provides flame and heat resistance with the added bonus of good retention of both strength and flexibility after exposure to thermal events.

PBI fibers can be used to make FR fabrics that provide excellent thermal protection as well being supple and comfortable. Used by TenCate Protective Fabrics in blends for the manufacture of fabrics that offer first-rate protection, PBI provides low heat transfer, FR protection and comfort all in one package, making it an ideal choice for the PPE that firefighters, military tactical personnel and other first responders need when the heat is on.

PBI fiber is manufactured by PBI Performance Products, Inc. and TenCate has partnered with them for the development of several fabrics  in the market today.
