What material is the coat's outer shell (PBI Max) made from?

• A. 100% Kevlar
• B. PBI Max 7.0 – 70% PBI/Aramid mix, 30% Kevlar
• C. 100% PBI
• D. Nomex

Answer: (B)

The outer shell fabric is a PBI Max blend designed to maximize heat resistance and durability. This specific material is a 7.0 version that combines 70% PBI/aramid with 30% Kevlar. The PBI portion provides exceptional thermal stability and maintains strength at high temperatures, while the Kevlar aramid adds toughness and abrasion resistance. Using this 70/30 blend achieves a balance of heat protection and wear life that pure Kevlar or pure PBI wouldn’t optimize as well, and it’s distinct from Nomex, which is a different aramid with its own properties.
