Heat Shield Barrier
A & R TARPAULINS, INC. - Outstanding Achievement
A Japanese company reached out to us to develop a heat shield barrier system that can be used for controlling nuclear power plants during natural disasters. The client needed to protect existing cable trays from high temperatures and fire, because during the Fukushima Daichi plant disaster, the controlling cable systems for the plant were destroyed by the fires, and thus the plant was unable to control its systems. The interior of the heat shield needed to withstand internal temperatures of 120 degrees C to 180 degrees C while the exterior (i.e. the flame exposed side) had to withstand a constant temperature of 1200 degrees C for a time period of up to 4 hours. We accomplished such and extreme requirement by using a combination of proprietary designed flexible ceramic and other materials that we had previously used in our aerospace applications. The assemblies were tested per ISO834 and passed all requirements including bringing down the temperature from 1200 degrees C on the flame exposed side of the assembly to 120 degrees C and 180 degrees C range on the inside of the assembly for a period that exceeded the 4 hour criterion.
