SafeCrest Explosion Suppressant Foam (ESF)

Crest SafeCrest reticulated polyurethane foams for explosion suppression and surge/noise mitigation (Explosion Suppressant Foam, ESF)
are environmentally-friendly materials for use on any vehicle where the possibility of fuel tank explosion exists, or where surge/noise mitigation is required.

• Proprietary manufacturing processes and special thermal reticulation techniques permit production of flexible skeletal foam structures with precisely controlled pore sizes and without cell membranes
• SafeCrest ESF is designed for use in rigid and flexible (bladder type) fuel tanks and fuel cells
• SafeCrest Class 2 materials exhibit anti-static properties down to -250 F, hydrolytic stability, and long service life
• Prevents catastrophic explosions of ignited fuel vapors in the tank caused by electrical arcing, overheating of internal components, lightning strikes, or by static electrical discharge
• Maintenance-free, contains no moving parts or electrical devices
• Passive operation, requires no action by operators or crews
• Efficacy (explosion suppression) is unaffected by fuel tank punctures, ruptures, fuel level, speed, attitude or altitude
• May be fabricated into any shape to conform to internal structural members and components such as pumps, valves, sensors, filters, fuel lines, etc.
• Mitigates fuel spray in the event of fuel tank rupture from compressive forces
• Effectively baffles fuel to control surging and eliminate sloshing
• Improves handling in high performance vehicles; eliminates fuel "slapping" noise in tank
• Quick, easy installation without special tools or skills; fuel wetting and low swelling characteristics of SafeCrest insure a snug fit without the need for oversizing of foam
• SafeCrest can be retrofitted to existing fuel tanks
