EXPERIMENTAL STUDY OF THE EFFECT OF THERMAL DAMAGE .

constructions in rocks after exposure to fire (Zhan and Cai, 2007). In the study of thermal damage of rock, the variation of thermo physical and mechanical properties of rock materials are required. Resistivity is a direct physical parameter of rock conductive properties, which indicates the level of resistance when electrical current flows ...

Polymer Properties Database

Melamine formaldehyde or melamine resin (short Melamine or MF) is a hard, very durable, and versatile thermosetting plastic (aminoplast1) with good fire and heat resistance. It is made from melamine and formaldehyde by condensation of the two monomers. Its good fire retardant properties are due to the release of nitrogen gas when burned or charred.
