PIP 906-PBH Double-Layer PBI Lenzing FR DuPont Nomex Nano Flex Particle Barrier Hood PROTECTION FROM TOXIC PARTICLES The additional layer of Nomex® Nano Flex to PIP's Particle Barrier Hood, 906-PBH stops up to 95% of submicron particles in the face and neck area that historically are known to be the most vulnerable and least protected. The result is up to 4X INCREASE IN PARTICLE BARRIER EFFICIENCY. THERMAL PROTECTION PERFORMANCE The combination of Nomex Nano Flex and an FR knit material in a the 906-PBH Firefighter Hood results in a 25% improvement in Thermal Protection Performance (TPP) compared to an FR knit material alone. Highest quality knitted "sock" style hoods that provide protection from flash fire hazards with added 2-ply construction for thermal insulation in cold weather conditions DuPont™ Nomex® Nano Flex is designed to block up to 95% of submicron carcinogen particles and other contaminants Lenzing FR® is a specialty viscose fiber, is flame resistant, and naturally derived from wood. It offers heat and flame protection and it's unique thermal properties combined with permanent flame resistance makes it a "Heat Protection Fiber". This fabric combination provides comfort and breathability The most cost effective solution to your NFPA requirements Meets or exceeds the standards of NFPA 1971 DuPont™and Kevlar® are trademarks or registered trademarks of E.I.
