Binders for materials based on glass and mineral fibers (overview)

The article presents an overview of the existing types of binders for heat and sound insulation made of glass and mineral fibers. The interest in the development or modification of binders for the manufacture of thermal insulation used in the transport, construction, and industrial sectors is due to increased requirements for their operational characteristics, as well as fire and environmental safety requirements. Trends in the development of binders for fibrous thermal insulation materials that meet modern requirements are indicated: thermal protection systems must have sufficient strength and flexibility to maintain their integrity during manufacture, transportation and installation in target volumes, sufficient elasticity to restore volume after compression, low specific gravity, low coefficient of thermal conductivity, resistance to flame, low smoke emission and resistance to moisture gain during heating and cooling.
