Hotblox B424 A lightweight (0.4 g/cc), high strength material for high temperature thermal insulation applications. Key Material Characteristics: Efficient near net shape production of complex parts Low thermal conductivity High strength Dielectric properties suitable for radome and antenna applications Can be co-molded with other materials. For example, to add an abrasion resistant surface or ablative surface, etc. Hotblox M323 Novel ablative ceramic for thermal protection systems. Key Material Characteristics: Efficient near net shape production of complex parts. At 800 °C, the material begins to ablate not allowing the temperature to rise above 800 °C. During ablation the dimensions of the material are retained. Key Tests Performed: Heat flux of 350 W/cm2 for 30 seconds during a LHMEL test at Wright Patterson Air Force base. Hotblox X323 Experimental solid-state ablative material for use in sensitive and enclosed environments where the evolution of gasses or liquids, typical of traditional ablative materials, can not be tolerated.
