Product Details

Otterlayer’s spats model LV1-APB have a high-heat resistant strip of Velcro at the back to hold them securely on the feet, and protecting the feet of wearers from sparks and molten metal splash.

Features of Otterlayer foundry/aluminized spats:

  • Velcro closure allows to easily and quickly remove these spats in case hot splash lands on them, reducing chance of injury from heat transfer further to shoes and feet underneath
  • 7” high from bottom to top of legging
  • 6” flare over top side of foot

Aluminized PBI is a knit blend of PBI® and para-aramid blend fibers with an aluminized coating. Despite being extremely lightweight and supple, aluminized PBI provides superior resistance to abrasions and chemical solvents. Its lighter weight and flexibility provide 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.

Protective properties of aluminized PBI clothing material:

  • Light, comfortable and flexible
  • Can withstand very high contact temperatures - withstands contact with objects at temperatures of 800°F+
  • Excellent thermal, abrasion and chemical resistance
  • Radiant heat protection - up to 2000°F
  • Not recommended for heavy molten metal splash

Fabric composition and characteristics:

  • PBI® / para-aramid blend fibers with aluminum coating
  • Fabric Weight: 7 oz. / sq. yd.
