Spark Deflectors, Hard Cap Shroud: 7 oz. Aluminized PBI® Blend

Aluminized PBI® is a knit blend of PBI® and paraaramid blend fibers, with an aluminized coating. Despite being extremely lightweight and supple, aluminized PBI® provides superior resistance to abrasions and chemical solvents, yet provides wearers with greater comfort and reduced fatigue. On its own, PBI® is an organic fiber with very unique properties. It was originally developed for NASA's Project Apollo, in response to the need for greater heat protection. It does not burn in air, melt, or emit toxic fumes. The addition of paraaramid blend provides extra strength and abrasion resistance.
