Ceramifying Polymers for Advanced Fire Protection

An interesting article :

Abstract: Ceramifying polymer materials have been developed by incorporating ceramic forming precursors into thermoplastics. These compounds can be processed on conventional plastic extrusion equipment to form sheets, profiles or coatings. In a fire situation, the polymer component is quickly pyrolized. However, a porous, coherent ceramic begins to form at sufficiently low temperatures to maintain the structural integrity of the material through to temperatures of over 1000°C. The ceramic forming systems can be adjusted to minimize dimensional changes, or to provide a degree of intumescence through entrapment of volatile gases from the polymer. This can produce a cellular structure with increased thermal resistance. Ceramifying polymer technology has already been commercialized for fire resistant cable coatings and shows promise for many other fire protection coating applications.
