Improved Fuel Resistant
Reticulated Foam Treatment

Response Technologies [RT] has developed a novel process for treating urethane open cell foams to improve fluid (fuel, water, oil, silicone coolant) resistance. Our solution has the potential to double the life of electrically resistive and safety aircraft fuel foam while allowing for wider use of bio-blend and ethanol fuels without degradation. The affected foams are used for: stealth technology, electrical shielding, and for fuel tank inerting and anti-sloshing.

The below image shows foam that is untreated and foam that has been treated with RT’s novel process and chemistry. The oil easily penetrates the untreated control and does not penetrate the treated. After several months, oil never penetrated the surface of the treated foam.
