Explosion Suppressant Foams

Reticulated Polyurethane

Reticulated polyurethane foams for explosion suppression and surge/noise mitigation are unique, environmentally friendly materials for use in fuel tanks of aircraft, boats, military vehicles, competition and emergency vehicles, automobiles and trucks - virtually any vehicle where the possibility of fuel tank explosion exists, or where surge/noise mitigation is required. Explosion Suppressant Foams (ESF) are ideal for use in fuel storage tanks and containers, both stationary and portable.

Explosion Suppressant Foam (ESF) has been used successfully in thousands of installations for over three decades. Proprietary manufacturing processes and special thermal reticulation techniques permit production of flexible skeletal foam structures with precisely controlled pore sizes and without cell membranes. The resultant “open pore” foam exhibits many unique characteristics and offers special advantages in fuel tanks for explosion suppression, fuel surge control, and noise mitigation applications of all kinds.

Qualified for all Military Uses

The U.S. Air Force, Navy, and Army (with the assistance of other agencies such as the Federal Aviation Administration) conducted extensive tests over many years - including exposure to HEI (High Explosive Incendiary) fire - to determine properties required in ESF to effectively protect aircraft and, at the same time, permit all fuel systems to function normally.

Applications

  • Mitigates fuel spray in the event of rupture from compressive forces and minimizes explosions by the ignition of fuel vapors in the tank caused by electrical arcing, lightning strikes, or static discharge.
  • Baffles fuel to control surging and eliminate sloshing, improves handling in high-performance vehicles and eliminates fuel ‘slapping’ noise in the tank.
  • Cost-effective solution with the lowest initial cost of any explosion suppression system; can be easily installed and retrofitted into existing fuel tanks, very low weight penalty, and requires no maintenance.
